Why do people remain in relationships that repeatedly hurt them? This article uses an IFS perspective to explore the protective parts behind codependent attachment, including fear, guilt, hope and responsibility. It explains why leaving can feel dangerous and how compassionate self-leadership can eventually support clearer, healthier and more authentic choices.
“Why don’t you just leave?”
It’s one of the most common questions people ask themselves when they remain in painful and toxic relationships. Indeed, it’s the question most of their friends and family would also ask. From the outside, it may be obvious as to why they should leave. The same patterns and cycles, the promises broken and little sign of change. People might get frustrated and accuse the person of not facing reality. Yet, leaving is rarely as simple as recognising that a relationship is harmful.
Someone may understand that something is very wrong, have all the awareness in the world and still be unable to act. One part may be exhausted and desperate for the life that freedom might bring, while another remains frightened, hopeful or burdened by shame and guilt. This internal guilt is often at the heart of codependency. Parts work, also known as IFS, offers a useful way of understanding this. Rather than viewing the person as weak or irrational, it asks: what is the part that cannot leave trying to protect?
The Protective Part Behind Staying
IFS suggests that we all have different parts within us. These are not different personalities, as some might think, but emotional positions shaped by experience. In a codependent relationship, one part may take responsibility for keeping everything together. It monitors other people’s moods, avoids confrontation, excuses harmful behaviour and continues trying to repair what is evidently and repeatedly broken.
This part may believe that leaving would be selfish or cruel and maybe believe that the other person won’t be able to survive without them. It may fear the other person will collapse or retaliate. Another part may remain attached to how the relationship might once have felt and remembers the honeymoon period feelings. It is not necessarily loyal to the current state of the relationship, but to the relationship it hopes will return. These parts are attempting to prevent something they believe would be even more painful.
When Responsibility Begins Early
Many codependent patterns begin long before all this happens. A child who grows up around unpredictability may learn to monitor the emotional environment carefully. They become sensitive and hyper-vigilant to tone, expression and changes in mood. They may try to keep the peace, comfort a parent or avoid becoming a burden. The child may well discover that being useful, helpful, quiet or compliant creates a sense of safety for them. As this happens, their own needs are pushed aside because there is no room for them. Over time, this can become an unconscious rule: other people’s wellbeing must come before their own. As an adult, they may experience this as loyalty, commitment or love. Beneath it, however, can be an old fear that something terrible will happen if they stop holding things together.
The Conflict Between Parts
This helps to explain why insight does not always lead to direct action. One part may recognise that the relationship is abusive or toxic. It sees the contempt, neglect or manipulation clearly and wants distance. Another part may respond with fear about bringing that forward. What if it causes pain, loneliness or financial hardship? What if it confirms the fear that being alone confirms that they were never truly worthy of love? A guilty part may argue that relationships require sacrifice or that leaving would mean abandoning someone who really needs them. A hopeful part may remember every apology or brief improvement and treat it as evidence that the relationship can still be saved, if they work or love a little harder. Several parts are therefore pulling in very different directions, each trying to protect the person from a different kind of pain. People often cannot fathom this as protection and see it as reality.
Why Pressure Often Fails
Directly telling someone they have to leave can intensify the conflict dramatically. When the parts feel judged, they often become more determined. They begin defending the relationship, the other person and minimising the harm or withdrawing from those who challenge them, including therapists. The same can happen internally. The person criticises themselves for being weak and stupid. This adds shame into the mix and adds layers of distress. IFS takes a more curious approach. What does the part believe would happen if the relationship ended? Whose wellbeing does it feel responsible for? What did it learn about love, responsibility and abandonment? Listening does not mean allowing that part to control every decision. It means understanding why it exists.
From Self-Abandonment to Self-Leadership
The aim is not to force someone to make immediate change. Nor is it to remain because a frightened part demands it. Self-leadership means approaching the situation from a steadier internal position. It allows fear to be heard without allowing it to determine the future. This may involve setting a boundary and observing what follows. It may mean seeking support or accepting that a relationship’s potential is not the same as reality. Sometimes, this can lead to both partners willing to work together. In other cases, the person recognises that they have been sustaining the relationship alone. Compassion for the part that stayed does not require continued submission to the pattern. People often stay in painful situations because some part of them believes staying is necessary for safety, belonging or moral worth. Change can only start when that part is neither shamed nor placed in charge. It is listened to, understood and helped to see that letting go may not be abandonment. It may be the beginning of returning to oneself.
Reflective Question
