When a relationship feels all-consuming, intense, and necessary for your happiness, it can be extremely difficult to distinguish between deep, sacrificial love and unhealthy codependency. Codependency is a behavioral pattern where one person sacrifices their own needs, identity, and autonomy to focus excessively on the needs, problems, or crises of another person
While healthy love is built on mutual support and two whole individuals choosing to share their lives, codependency creates a relationship where your partner’s need for you becomes the foundation of your self-worth. This dynamic is especially common in relationships involving chronic illness, mental health issues, or substance use disorders (SUD).
This guide will provide a definitive framework for recognizing these patterns.
What is Codependency?
The Diagnostic and Statistical Manual of Mental Disorders (DSM) is an authoritative guide that healthcare professionals use to diagnose mental illness. However, the DSM does not recognize codependency as a distinct personality disorder. The term codependency originated from drug and alcohol addiction, and it has various, sometimes vague definitions. The simplest explanation is that codependency is seeking love based on feelings of insecurity or inadequacy. A codependent person looks to their partner to repair their self-esteem, alleviate their pain, and complete their inner emptiness. What ends up happening is that the partner cannot be the person they are. Instead, they are forced to fulfill a role the codependent partner has chosen for them, i.e., to provide unconditional love and security. Yet, there is never enough love. The codependent person keeps working to try and please their partner to ensure they get the love they crave. It becomes a self-perpetuating habit with obsessive thoughts and compulsive behaviors. That’s why codependency is also sometimes called relationship addiction or love addiction.
Is Love Addiction a Mental Illness?
Although love addiction may not be considered a mental illness as the Diagnostic and Statistical Manual of Mental Disorders doesn’t classify it as such yet, scientific research has indicated that problematic feelings about love can have an effect on the brain that is similar to the negative feelings experienced as a result of substance use disorder (SUD). A 2016 study compared brain scans of individuals with drug addictions to those with love addictions. The study found that both forms of addictions activated similar areas of the brain’s reward system, especially those areas that have a high amount of dopamine. This suggests that SUDs and behavioral addictions, like love addiction or internet addiction, affect the brain’s activity in much the same way.
How Can You Tell the Difference Between Love and Codependency?
The key to distinguishing between healthy love and codependency lies in examining the core motivation behind your actions and the balance of power in the relationship.
1. What Is the Motivation Behind Your Actions?
Healthy love and codependency often look the same on the surface, but the internal drivers are entirely different.
- In Love: Actions are motivated by secure attachment, empathy, and genuine desire for the partner’s growth and happiness. You act from a place of fullness, not a place of need.
- In Codependency: Actions are motivated by fear, control, and a desperate need for validation and self-worth. You act from a fear of abandonment or from a need to feel important.
| Relationship Dynamic | Motivation in Healthy Love | Motivation in Codependency |
| Giving Help | Desire to support a partner’s success. | Fear that partner will leave or fail without you. |
| Setting Boundaries | Mutual respect for personal space and time. | Avoided entirely, or set only to manipulate. |
| Focus | Shared goals; personal hobbies are maintained. | Partner’s problems or needs become primary focus. |
| Conflict | Healthy debate aimed at mutual resolution. | Avoided at all costs; surrender to keep the peace. |
2. How Does Your Self-Worth Relate to the Relationship?
A major indicator of codependency is when your sense of self-worth is entirely external
- In Love: Your self-esteem is internal and stable. Your partner adds to your life, but does not define it.
- In Codependency: Your self-worth is external and conditional. It rises and falls entirely based on your partner’s approval, success, or dependence on you. You only feel valuable when you are sacrificing for them.
If you feel completely lost or worthless when your partner is happy and independent, or if you actively feel the need to create problems to be needed, the dynamic is likely codependent.
3. What Role Do Boundaries Play in the Relationship?
Boundaries are the clear, verbal limits you set for what you will and won’t accept.
- Love requires healthy boundaries. Partners respect personal space, time with friends, and independent goals. If one partner crosses a line, the other communicates it calmly.
- Codependency eliminates boundaries. The codependent merges their identity with the other person, often taking on their partner’s feelings, problems, and moods as their own. Boundaries feel selfish, threatening, or impossible to enforce.
An extreme sign of this is taking responsibility for a partner’s negative behavior, such as apologizing to an employer for their drinking or paying their debts because you fear the consequences they will face.
8 Defining Signs of Codependency
These signs indicate that your relationship structure may be unhealthy and codependent:
- Extreme People-Pleasing: You constantly seek approval and validation from your partner, often saying “yes” when you desperately want to say “no”.
- Taking Responsibility for Others: You feel compelled to “fix” your partner’s problems, manage their life, or shield them from the natural consequences of their actions (i.e., enabling).
- Low Self-Esteem: You base your entire identity and value on how much you sacrifice or how dependent your partner is on you.
- Difficulty Setting Boundaries: You avoid conflict and sacrifice your own needs to maintain artificial peace.
- Perfectionism and Control: You feel the need to control your partner’s actions, friends, or environment because you believe their failure reflects badly on you.
- Neglecting Your Own Needs: Your personal goals, hobbies, and friendships are abandoned or ignored in favor of tending to your partner’s every need.
- Emotional Reactivity: Your mood is entirely dependent on your partner’s mood; if they are having a bad day, you immediately feel depressed or anxious.
- Fear of Abandonment: You stay in unhealthy, sometimes abusive, situations because the fear of being alone is more terrifying than the pain of the relationship.
How to Shift from Codependency to Interdependence
The goal is not isolation, but achieving a state of interdependence, where two people who are emotionally and psychologically whole choose to share their lives. This shift requires dedication and often professional support.
1. Prioritize Your Own Self-Care and Identity
This is the most critical first step.
- Reclaim Time: Dedicate a specific amount of time each week to hobbies, friends, or interests that have nothing to do with your partner.
- Identify Your Feelings: Practice identifying your emotions without immediately reacting to your partner’s. Use language like: “I feel [emotion] because [reason]”.
- Establish a Separate Life: Re-engage with old friends and develop personal goals that are independent of your relationship goals.
2. Practice Setting and Maintaining Boundaries
Boundaries are the hallmark of respectful love. Start small and practice consistency.
- Communicate Limits: Clearly state what you will and will not do. For example: “I will not bail you out financially, but I will help you research budgeting courses.”
- Be Consistent: When a boundary is crossed, follow through with the stated consequence without guilt or anger.
- Allow Consequences: The hardest part of this shift is allowing your partner to experience the natural consequences of their own actions. This is how they grow; shielding them is enabling.
3. Seek Professional Support
Codependency patterns are often deeply ingrained and linked to early life experiences. They can be incredibly difficult to break alone.
- Individual Therapy: Therapists specializing in trauma, attachment theory, and codependency (often utilizing Cognitive Behavioral Therapy(CBT)) can help you unpack the root causes of your people-pleasing and fear of abandonment
- Support Groups: Groups like Co-Dependents Anonymous (CoDA) offer peer support and a 12-step framework for healing from codependency.
- Family Counseling: This can be invaluable if your partner is willing to participate, helping to reset the relationship’s rules and communication patterns.
Frequently Asked Questions (FAQ)
What is the primary cause of codependency?
Codependency often stems from growing up in a dysfunctional family system (e.g., a home with addiction, emotional neglect, or abuse) where a child had to take on adult responsibilities, become a caretaker, or constantly seek parental approval to feel safe. This learned pattern of sacrificing self for others then transfers to adult relationships.
Can a relationship survive codependency?
Yes, a relationship can survive and thrive, but only if the individuals commit to change. This requires the codependent person to focus on personal recovery (building self-worth and boundaries) and the focus person to accept responsibility for their own life and stop exploiting the codependent dynamic. Professional counseling is almost always required to successfully reset these deeply rooted patterns.
How does codependency relate to addiction?
Codependency is rampant in relationships affected by addiction. The codependent person often takes on the role of the “rescuer,” managing the addict’s crises, making excuses for their behavior, and prioritizing the addict’s needs over their own recovery. This enabling actually hinders the addict’s recovery by preventing them from facing the true consequences of their substance use.
Is codependency an official diagnosis?
No, codependency is not a recognized clinical diagnosis in the latest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). It is a recognized and widely studied psychological and behavioral construct used in therapy, counseling, and recovery programs.

The Bottom Line
A healthy love relationship cannot be based on unhealthy relationship dynamics. Knowing the difference between love and codependency is essential to creating and sustaining genuine connections. While love addiction stems from negative self-beliefs that form due to childhood trauma and low self-worth, codependency can come from a lack of external validation and fear of being alone. Both scenarios are far from normal, as excessive focus on the partner and compromised self-care can be detrimental to one’s own emotional and mental well-being. To overcome codependency, you must end the love addiction. Reach out to a mental health professional who can guide you through the process of breaking free from the cycle of indulging in people-pleasing behavior and prioritizing other people’s needs over your own needs and offer you additional resources like therapy and support groups to access judgment-free environment. Practicing self-awareness, self-love, and mindfulness is key. You can start by setting boundaries and acknowledging your thoughts and behavioral patterns. This will empower you to change your codependent patterns. Other techniques like cognitive behavioral therapy and repeating affirmations can further help change ineffective behavioral patterns and steer away from codependency. Remember, being codependent on your partner does not equate to love. Taking proactive steps to address codependent behavior is necessary to truly love and be loved.
