Codependent relationships are characterized by a significant imbalance in the exchange of emotional and psychological support.
In these relationships, one person feels an overwhelming sense of responsibility for the other person’s well-being and happiness, often at the expense of their own needs.
Codependency is a dynamic process that typically involves two primary roles: the enabler and the enabled.
The enabler is the person who takes on a caretaking or protective role in the relationship. They often end up with a partner who shows a dysfunctional pattern, such as substance misuse or narcissistic tendencies.
Each role feeds the other.
The enabled person relies on the enabler to meet their needs and rescue them from their problems. This person often becomes increasingly dependent on the enabler. That dependence extends to emotional support, financial assistance, and other parts of daily life.
The codependent dynamic arises because these two roles reinforce each other’s patterns. The enabled person’s struggles trigger the enabler’s need to care for and protect them, and the enabler’s caretaking reinforces their reliance on them in turn.
Key Takeaways
- Two Roles: Codependency centers on two interlocking roles: an enabler who takes on a caretaking, fixing role, and an enabled person who comes to rely on them for support.
- Not Healthy Caring: Unlike healthy caring, codependency is driven by fear of abandonment, a need for approval, or a compulsion to control or fix the other person, not by simple empathy.
- Common Signs: Low self-esteem, difficulty saying no, excessive caretaking, trust and control issues, and weak personal boundaries are among the most common signs.
- Family Origins: Codependent patterns often trace back to childhood, especially growing up with addiction, overprotective parenting, neglect, or abuse in the family.
- Real Harm: Left unaddressed, codependency can perpetuate a partner’s dysfunction and unbalance power in the relationship, and has been linked to depression, anxiety, and other mental health difficulties.
- Recovery Is Possible: Recognizing the pattern, building self-awareness, and setting clear boundaries are consistently identified as the first steps toward healthier, less codependent relationships.
Signs of a Codependent Relationship
Two partners who feel they are nothing without each other are a common trope in literature, songs, television, and movies. They derive their entire sense of self from one another. Real life rarely matches the trope.
However, this portrayal actually describes a codependent and unhealthy relationship dynamic.
“Codependent relationships are a specific type of dysfunctional helping relationship in which one person supports or enables the other person’s underachievement, irresponsibility, immaturity, addiction, procrastination, or poor mental or physical health.”
Codependency Anonymous (2019)
It’s natural for couples to rely on each other for emotional support and companionship. But in a healthy relationship, each person also maintains their own sense of identity, self-esteem, and independence.
The following are some signs of a codependent relationship:
1. Excessive Caretaking
Codependents may feel compelled to take care of and fix the problems of the other person, often at the expense of their own needs. They may take on an excessive and unhealthy level of responsibility for the other person’s life, making decisions for them and attempting to control their choices.
In this dynamic, one person is in distress and takes on the role of the enabled, while the other takes on the role of the caretaker, or the enabler.
The enabler enjoys being needed.
They derive their sense of closeness and love from helping and rescuing the enabled person, and find a sense of purpose and identity in being a caretaker.
Caretaking can look like healthy caregiving on the surface, since both involve attending to someone else’s needs. The difference lies underneath.
Caregiving comes from empathy and is given without expecting anything back. Caretaking is driven by a need for validation and a fear of not being needed.
The two motivations feel different from the inside.
The enabled person, on the other hand, feels loved and validated when they are receiving help and support from the enabler.
They may become dependent on this support to cope with their distress. That dependence reinforces their own sense of inadequacy.
The two individuals become interdependent in an unhealthy way.
The enabler’s identity and self-worth become tied to their caregiving role, while the enabled person’s sense of self becomes linked to their need for help and support.
2. Low Self-Esteem
Codependent individuals typically have low self-worth and seek validation and approval from their partner to feel better about themselves.
As a result, they will go to great lengths to meet their partner’s needs and avoid conflict, in the hope of gaining affirmation and validation.
They may feel valuable only in that role. Outside it, they can feel a sense of emptiness or worthlessness.
This often fuels a fear of abandonment. Codependent individuals may go to great lengths to prevent any action that might push their partner away, even compromising their own needs and boundaries in the process.
3. Enabling Behavior
Enabling behaviors in a codependent relationship typically involve actions that allow or perpetuate the codependent dynamic and dysfunction.
For example:
- Giving money to the enabled person to cover their expenses
- Making excuses or covering for the enabled person when they fail to fulfill their responsibilities
- Continually bailing the enabled person out of difficult situations caused by their actions
- Tolerating mistreatment, abuse, or neglect from the other person without setting boundaries
- Offering constant emotional support and reassurance, even when the other person’s behavior is harmful
Enabling may also involve supporting or even participating in the other person’s self-destructive habits or unhealthy behaviors in an attempt to maintain the relationship (e.g., substance misuse).
4. Difficulty with Assertiveness
Codependents often struggle to assert themselves, say no, or express their own feelings and needs freely.
This struggle often stems from a fear of rejection, conflict, or abandonment as they fear that asserting themselves will lead to conflict or disapproval from their partner.
Saying “no” can be especially challenging for codependents because they think that doing so will result in the other person’s anger, disappointment, or withdrawal of affection.
Codependents may find it hard to openly express their own feelings, especially if those feelings conflict with the desires or expectations of the partner.
Instead, they suppress their emotions to avoid upsetting the other person.
5. Trust and Control Issues
Codependents may resort to controlling or manipulative behaviors to maintain the relationship or cope with their own fears and insecurities. These behaviors can be driven by a deep-seated fear of abandonment, a need for validation, or a desire to keep a sense of power in the relationship.
Manipulation can take several forms.
Some codependents use guilt, passive-aggressive tactics, or emotional manipulation to make their partner feel responsible for their happiness. Others isolate their partner from friends and family, limiting their social connections and support systems.
Feeling in control may soothe their own insecurity. In the long run, though, these behaviors are usually counterproductive: they erode trust, create resentment, and deepen the relationship’s dysfunction.
6. Lack of Boundaries
Lacking boundaries can be a sign of a codependent relationship.
Here are some ways a lack of boundaries can manifest:
- Codependents may find it extremely challenging to say “no” to their partner’s requests or demands
- They frequently sacrifice their own well-being, interests, and desires to meet their partner’s needs
- Codependents may take on responsibilities that should be handled by their partner
- Codependents may engage in overprotective or controlling behaviors, attempting to manage their partner’s life, decisions, or actions
- Personal self-care and well-being often take a back seat to prioritize their partner’s needs and happiness
An Expert’s View: The “Hero Complex”
As the therapist Esther Perel explains on her podcast Where Should We Begin?, this caretaking pattern often overlaps with what she calls a ‘hero complex,’ or ‘rescue fantasy.’
Perel traces the pattern back to earlier life, often childhood.
It began, she says, when a person either succeeded in rescuing a struggling family member, or never got the chance to.
Some people come to feel that others reach out to them mainly “when they need me because I can do something for them,” according to Perel.
That’s rarely about love for who they are.
Being treated as “the nurse,” “the counselor,” or “the coach” rather than as a full partner rarely holds up, she observes.
Eventually, the person doing the rescuing starts wondering whether there will “ever be space for me.”
What is the Difference Between Codependency and Caring?
Codependency and caring both involve emotional and supportive behaviors in a relationship, but they differ in motivation, boundaries, and effect on the other person.
What Healthy Caring Looks Like
Healthy caring is motivated by genuine love, concern, and empathy for the other person’s well-being.
It supports and nurtures the relationship without sacrificing one’s own well-being or identity.
Caring individuals maintain their independence within the relationship. They keep their own interests, goals, and self-esteem, and do not rely on the relationship for their sense of worth.
A caregiver also respects the other person’s autonomy.
They do not try to impose their own preferences, and they keep practicing their own self-care, rather than losing themselves in caring for someone else.
Support is given because it is wanted, not because something is expected back in return.
A useful test is whether the relationship would survive if the helping stopped. For a genuine caregiver, the answer is usually yes.
What Codependency Looks Like
Codependency, by contrast, is often driven by a fear of abandonment, a need for external validation, or a compulsion to control and fix another person’s problems.
Codependents may feel that their self-worth is tied to their ability to care for and please the other person.
Codependent individuals become emotionally enmeshed with the other person, losing their sense of independence and self-identity. They may feel incomplete without the relationship.
This pattern often shows up as neglecting their own self-care, and struggling to say no even when a request feels unreasonable.
Where a caregiver’s support is unconditional, a codependent’s help is often expected to be met with gratitude and validation, which tends to lead to disappointment when it isn’t.
The same test applies in reverse. If the relationship would not survive without the caretaking, that is a sign of codependency rather than healthy care.
Codependency vs. Interdependency
Codependency and interdependency both involve relying on another person. But interdependency, from ‘inter,’ meaning reciprocal, describes a healthy, balanced mutual reliance built on shared goals, while codependency does not.
| Codependency | Interdependency | |
|---|---|---|
| Basis | Fear of abandonment, need for external validation, or a compulsion to control or fix the other person | Common or shared goals, with both partners as equals |
| Boundaries | Enmeshed — little distinction between one partner’s feelings and needs and the other’s | Respected — both partners maintain separate interests and needs alongside the relationship |
| Self-worth | Tied to the relationship and to the caretaking or enabled role | Stable and independent of the relationship |
| Communication | Avoidant, passive-aggressive, or manipulative, often driven by fear of conflict | Open and honest, addressing conflicts and differences constructively |
Put simply, codependency involves an unhealthy, imbalanced, often-enabling relationship. Interdependency is a balanced, supportive, and mutually satisfying one.
Types of Codependent Relationships
Codependent relationships can manifest in various forms, and they are not limited to just one type. Here are some examples of common codependent relationships:
Caretaker (Enabler) and Addict
In this type of codependent relationship, one person assumes the caretaker role. They feel an intense need to take care of, rescue, and “fix” their partner, who is usually struggling with addiction or substance abuse.
These individuals often derive their self-worth from their caregiving role and believe that their partner’s recovery hinges on their efforts.
The caretaker may engage in enabling behaviors, such as covering up the addict’s actions, making excuses, or providing financial or emotional support that indirectly sustains the addiction.
The person struggling with addiction in this dynamic may become increasingly dependent on their caretaker for support, financial stability, and to rescue them from the consequences of their actions.
Overbearing Parent and Dependent Adult Child
In this type of codependent relationship, one partner assumes the role of an overbearing and controlling parent figure.
They may dictate the adult child’s decisions, make choices on their behalf, and maintain an unhealthy level of control.
The other partner takes on the role of a dependent adult child who seeks constant approval, validation, and care from the overbearing parent figure.
They may struggle to assert their own independence and autonomy.
The overbearing parent often feels the need to protect and control the adult child, believing they know what is best. The dependent adult child, in turn, may fear rejection or abandonment if they assert their independence.
Rescuer and Victim
The rescuer in this codependent dynamic sees themselves as the savior, always trying to help and save their partner who portrays themselves as the victim.
The person taking on the victim role often portrays themselves as helpless and perpetually in need of rescue.
This person may appear unable to take responsibility for their own actions, while the rescuer is consistently over-involved in trying to alleviate their partner’s suffering.
The rescuer is motivated by a desire to make the victim happy, save them from their problems, and gain their love and approval.
The victim, in turn, may use the rescuer’s care to maintain their sense of dependence and control in the relationship.
Codependency Between Parent and Child
Codependency doesn’t only show up between romantic partners.
It can also develop between a parent and a child, when the parent relies on the child for emotional support, validation, or a sense of purpose.
This reverses the direction support is normally expected to flow in a family.
This pattern can be harder to recognize than codependency between partners.
The reversal is easy to miss.
A certain amount of caretaking is a normal, even necessary, part of parenting a young child.
This dynamic often traces back to the parent’s own family of origin.
A parent who grew up in a dysfunctional family, or whose own emotional needs went unmet, may unconsciously look to their own child to meet those needs instead.
That can create a cycle.
The child comes to feel responsible for the parent’s emotional wellbeing, and learns to put the parent’s needs above their own.
This pattern commonly persists into adulthood.
It makes it harder for the grown child to assert their own needs, set boundaries, or prioritize their own self-care.
Four recurring patterns describe how this typically shows up.
- Controlling Behavior: A threatened, codependent parent may guilt-trip or emotionally pressure a child to prevent them pulling away, teaching the child to fear making independent choices.
- Boundary Confusion: The parent struggles to separate their own emotions from the child’s, treating the child’s successes or failures as reflections of their own worth.
- Sacrificial (Martyr) Parenting: The parent constantly emphasizes their own sacrifices for the child, which can teach the child that love depends on self-sacrifice.
- Overinvolvement: The parent micromanages the child’s life, from monitoring activities to making decisions for them, leaving the child insecure about deciding things independently.
Healthy parent-child relationships rest on a different foundation.
Suldo (2009) describes it through four qualities: safety, unconditional love, mutual respect, and open communication.
In a codependent parent-child relationship, the child’s needs and individuality are not fully respected.
The child learns to fear rejection if they assert them.
That pattern can shape their behavior well beyond childhood.
Because these patterns are modeled at home, a child who grows up playing this role may never question it, since it has become an ordinary part of their identity.
Why is Codependency Problematic for a Relationship?
Codependency is problematic for a relationship for several reasons:
Skewed Power Dynamics
Codependent relationships are often marked by an imbalance of power and control. One partner typically takes on a dominant, controlling role, while the other becomes more submissive and dependent.
The dominant partner often believes others can’t take care of themselves, so they take charge, making most of the decisions and setting the rules.
Their intentions are not always malicious.
Even so, some use their position of power to control or manipulate the other person, through unilateral decisions, emotional pressure, or coercive behavior.
The submissive partner, meanwhile, often sacrifices their own autonomy to maintain the relationship.
Resentment tends to build over time.
They may give up making decisions, suppress their own desires, and lose their sense of self to please the dominant partner.
The submissive partner may feel increasingly controlled and powerless. The dominant partner, in turn, can become overwhelmed by the responsibility of holding the relationship together.
Unhealthy Boundaries
Boundaries are an important part of a healthy relationship. In codependent relationships, personal boundaries are often weak or nonexistent.
This can result in violations of individual space and privacy, leading to further conflict and emotional turmoil.
A loss of boundaries can also result in a loss of personal autonomy.
Codependents may feel compelled to constantly accommodate their partner’s needs and desires, neglecting their own autonomy and sacrificing their individuality.
This can lead to feelings of unfulfillment and dissatisfaction.
Negative Reinforcement of Unhealthy Behaviors
Negative reinforcement of unhealthy behavior is a common pattern in codependent relationships. It happens when one partner, often the codependent one, unintentionally reinforces or enables the other’s destructive behavior.
The pattern is easy to miss.
For example, a codependent partner may excuse the other’s addiction, irresponsibility, or emotional manipulation, which perpetuates the destructive pattern.
This sustains the other person’s dependency on the codependent partner.
The partner engaging in destructive behavior becomes increasingly reliant on the codependent to keep going without facing real consequences. The result is a cycle of dysfunction that is hard to break.
Loss of Individuality
Codependency tends to lead to a loss of identity because the codependent partner will put the other’s needs, feelings, and opinions above their own.
They often have trouble making their own decisions and find it hard to identify what they want and need.
Their self-worth is based on being loved and validated by the other, and they will suppress their feelings to please them.
Both partners become so enmeshed in the relationship that they have difficulty maintaining their own interests, goals, and autonomy.
Poor Communication
Codependents often repress their own feelings, needs, and desires to avoid conflict or to keep their partner happy.
This leads to emotional suppression.
It also leaves a lack of healthy communication in the relationship.
Codependency can interfere with problem-solving too, since the focus tends to fall on avoiding conflict rather than resolving it.
A small disagreement can trigger a large fight.
When issues do come up, communication in codependent relationships tends to swing between two extremes: avoiding the problem entirely, or letting it escalate quickly into an argument.
A partner might stay silent through repeated frustration, only for a small disagreement to trigger a much bigger argument later.
Real problems go unspoken either way, or get resolved poorly when they finally surface.
Long-Term Relationship Health
Over time, codependent relationships tend to become more dysfunctional and less fulfilling.
This leads to dissatisfaction, resentment, and sometimes relationship breakdown.
Codependency has also been linked to wider mental health difficulties, including depression, eating disorders, anxiety, and compulsive behaviors such as OCD.
More recent research links it to poorer coping as a couple, and to lower relationship and life satisfaction.
It is not a healthy foundation for a long, satisfying relationship.
Its effects can also reach beyond the couple. Children who grow up watching a codependent relationship may internalize the pattern as normal, unconsciously carrying it into their own adult relationships.
That is one reason recognizing the pattern early, in any relationship, matters so much for its long-term health and stability.
Personal Experiences
Bacon et al. (2018) conducted a qualitative study exploring the lived experience of codependency from the perspective of self-identified codependents. Participants were given pseudonyms to protect their identities.
Selma described a long search for something that could explain her difficulties: “I needed something to explain it, I needed something to explain everything.”
“And it (codependency) doesn’t explain nothing, it explains everything!”
She used a recurring image for the loss of a stable identity too. “It is like the chameleon,” she said, “trying to fit in with every situation rather than allowing myself to be who I am.”
Misha connected her codependency directly to a family history of addiction: “I think all addiction patterns come from codependency.
Codependency is the mother ship of all addictions!”
Helena used the image of a seesaw to describe how her life swung between extremes.
“I can swing from self-care to self-deprivation,” she said.
“If I push, and put too much weight on one end, I feel very out of control. But if it is balanced, it would be easier.”
These accounts describe one small group’s own experience of codependency. They are not a general claim about how everyone who identifies with the term experiences it.
How to Avoid Codependency in Relationships
Avoiding codependency in relationships is important for maintaining healthy, mutually satisfying connections.
Codependent relationships usually happen between a person with dysfunctional behavioral patterns (e.g., addiction) and a person with a dysfunctional way of relating to others (e.g., low self-esteem).
That means, to avoid codependency, it is important to work on your own challenges and issues first.
The following elements exist in a healthy relationship:
- Clear and respected boundaries
- Mutual respect
- Independence and autonomy
- Open and effective communication
- A desire to be together rather than a need to be together
- Emotional support and validation
- Healthy conflict resolution
- Shared common values and life goals
To avoid codependency, it is thus important to:
- Build Self-Worth: Your self-worth should come from within, not only from your partner’s validation.
- Set Boundaries: Learn to say no when necessary, and communicate your needs and limits openly.
- Respect Their Choices: You can love and support your partner, but they are responsible for their own decisions.
- Keep Outside Interests: Maintain your own hobbies and goals outside of the relationship.
- Reflect on Your Needs: Check in regularly with your own needs, desires, and feelings.
- Support Mutual Independence: Foster your own independence while supporting your partner’s.
- Communicate Openly: Develop the skills to express your feelings and needs honestly.
Critical Evaluation
Codependency is a widely used idea. But psychologists don’t fully agree on what it is, or how well it holds up as its own concept.
The sections below weigh the evidence for and against it.
Is Codependency a Well-Established Concept?
Codependency has no single agreed clinical definition, and it does not appear in the DSM, the standard manual used to diagnose mental health conditions.
Researchers have described at least three competing explanations for it.
One treats it as a disease, an illness in its own right.
Another locates it in stable personality traits.
A third sees it as something jointly produced by both partners’ behavior.
The field has never settled between these views.
Some of the most specific claims about codependency’s harms also rest on thin evidence.
The evidence is surprisingly old.
The links to depression, eating disorders, and general psychological difficulty each come from a single older study. Two of those studies were never even published in a peer-reviewed journal.
Even the richest account has limits.
It is a 2018 interview study of eight people attending codependency support groups. Their views may have been shaped by the very support-group language the study set out to describe.
How Codependency Compares to Other Psychological Theories
Codependency overlaps with several theories that were developed independently of it, and that rest on a larger evidence base.
In adult attachment theory, a ‘preoccupied’ attachment style describes high anxiety about a partner’s availability, alongside strong approval-seeking and fear of abandonment.
That resembles codependency’s own fear-of-abandonment features (Bartholomew & Horowitz, 1991).
Family systems theory offers a more direct rival account.
Murray Bowen (1978) argued that people vary in their ‘differentiation of self’: the ability to hold onto their own thoughts and feelings while staying close to others.
People with low differentiation are more likely to become ‘fused’ with another person’s emotional state.
That maps onto what the codependency literature calls enmeshment.
Across a sample of 318 adults, lower differentiation of self predicted codependent behavior more strongly than a couple’s general relationship adjustment did (Lampis, Cataudella, Busonera, & Skowron, 2017).
That is direct evidence for Bowen’s older theory.
A third account comes from psychoanalyst Donald Winnicott’s (1960) idea of the ‘false self.’
A child who is not adequately recognized by a caregiver learns instead to comply with and anticipate that caregiver’s needs, building an outwardly adaptive but inauthentic self.
Researchers studying codependency have read participants’ own description of a shifting, ‘chameleon-like’ sense of self as an illustration of exactly this pattern.
Contemporary Research
Most recent research on codependency falls into two groups.
One is small interview studies exploring what the experience feels like from the inside.
The other is quantitative research testing how codependency relates to relationship functioning and wellbeing.
Neither a meta-analysis nor a randomized controlled trial of codependency exists yet.
The picture is still developing, not settled fact.
The most detailed recent study surveyed 246 adults in Hungary, using validated questionnaires that measured codependency, dyadic coping (how a couple manages stress together), relationship stress, and life satisfaction.
Codependency was reliably linked to more negative dyadic coping, and to viewing the relationship as more problematic. It had no reliable link to positive, supportive coping at all.
That mattered more than closeness.
Codependent attitudes reduced life satisfaction indirectly, through this negative coping style, rather than acting on it directly (Happ, Bodó-Varga, Bandi, et al., 2023).
A related strand of research asks where codependency comes from.
Consistent with the family-systems account above, the same 318-adult study found that low differentiation of self predicted codependent behavior more strongly than general relationship adjustment did (Lampis et al., 2017).
Most recently, a 2025 study of 233 women found that codependency severity correlated with anxiety, depression, and obsessive-phobic symptoms (Kolenova, Kukulyar, & Denisova, 2025).
That study, like much of the field, recruited only women.
It extends a gender-skewed evidence base rather than resolving it.
Taken together, this evidence supports codependency as a measurable pattern with real correlates for relationship functioning and psychological distress.
Every such study is correlational or small-scale, though.
Claims that codependency causes these outcomes, rather than simply accompanying them, remain unproven.
