Why do I keep ending up in unhealthy relationships?

Many people find themselves asking this question after the end of a difficult relationship. Perhaps they have experienced the same dynamics several times: becoming involved with someone who is emotionally unavailable, feeling responsible for keeping the relationship together, tolerating behaviour that they know is hurtful, or becoming increasingly anxious about whether the other person still cares. With some distance, the pattern can seem obvious. Yet when it happens again, it can be difficult to understand why something that was once so clear becomes much harder to see from within the relationship.

It is easy to interpret this as a problem of poor judgement. We may tell ourselves that we simply keep choosing the wrong people, that we should have recognised the warning signs earlier, or that there must be something about us that attracts unhealthy relationships. These explanations can be particularly painful because they place the responsibility entirely within the individual, without considering the psychological processes that influence who we are drawn to and what we come to experience as familiar.

When Familiarity Feels Like Connection

Our relationships are shaped by more than conscious choice. From early in life, we develop expectations about what it means to be close to another person, how much we can depend on someone, whether our needs will be taken seriously, and what we might have to do to maintain connection. These expectations are not necessarily conscious beliefs that we can easily identify. They can become part of the way we experience relationships, influencing what feels comfortable, what feels threatening, and what we are prepared to tolerate.

For this reason, familiarity and emotional safety are not always the same thing. A person may have grown accustomed to relationships in which affection was inconsistent, emotions were difficult to express, or they had to take responsibility for other people's needs. Later in life, a relationship that contains some of these familiar dynamics may not immediately feel unhealthy. It may instead feel recognisable. There can be a sense of chemistry or intensity that is difficult to explain, partly because the emotional experience itself is familiar.

This does not mean that people consciously seek out relationships that will hurt them, nor does it mean that our early experiences determine who we will choose as adults. Rather, it suggests that we do not enter relationships as blank slates. We bring previous experiences with us, including assumptions about ourselves and other people that may influence how we interpret what happens between us.

When We Try to Repair Something Through Someone Else

Sometimes we find ourselves trying to obtain something in a relationship that was difficult to obtain elsewhere. To finally feel chosen. To finally be enough. To finally have someone stay. To finally be understood. Without realising it, the relationship can become about more than the person in front of us. It can become an opportunity to repair something much older.

This can make a relationship particularly difficult to walk away from. We may not only be attached to the person or to the relationship as it currently exists, but also to the possibility that this time things might turn out differently. If we can finally be chosen by someone who is uncertain about us, or loved by someone who struggles to show love, perhaps something painful from the past will feel resolved. The difficulty is that we can become invested in what the relationship represents rather than what it is actually offering us.

This is also where hope can become complicated. We may recognise that the relationship is not meeting our needs, while continuing to believe that if we are patient enough, understanding enough, or find the right way to communicate, something will eventually change. We are then no longer responding only to the relationship in front of us, but also to the possibility of what it could become.

When We Slowly Lose Sight of Our Own Needs

There is also a quieter process that can take place within unhealthy relationships. We may gradually begin to adapt ourselves in order to preserve the connection. At first, the changes may seem insignificant. We might avoid raising something because we do not want an argument, become more accommodating because the other person is under pressure, or convince ourselves that a particular behaviour is not important enough to make an issue of. Over time, however, these small adaptations can accumulate. We may become increasingly disconnected from our own needs while becoming more focused on understanding the other person's.

This can be difficult to recognise because the adaptations themselves may initially feel like signs of love, patience or maturity. Being understanding is not inherently unhealthy, and relationships inevitably require compromise. The difficulty arises when understanding another person consistently comes at the expense of understanding ourselves.

Relationships also have a way of bringing our vulnerabilities to the surface. Someone's distance might activate fears of abandonment. Someone's criticism might awaken feelings of inadequacy. Someone's dependence might make us feel responsible for their wellbeing. Someone's closeness might feel suffocating. When these feelings become intense, we may respond in familiar ways: pursuing, withdrawing, pleasing, controlling, shutting down or becoming overly independent.

Why do I keep choosing people like this?

This is why asking, “Why do I keep choosing people like this?” may not always be the most useful question. It places all the attention on the person we have chosen, when an equally important part of the pattern concerns how we behave once we become attached. What happens to our boundaries when we are afraid of losing someone? How comfortable are we with expressing our needs? What do we do when another person's behaviour disappoints us? Are we able to tolerate the possibility that someone may be unhappy with us, or does their disapproval become something we feel compelled to prevent? These questions move us away from blaming ourselves and towards understanding the emotional patterns that can develop within relationships.

It is also important to recognise that unhealthy relationships are not necessarily unhealthy from the beginning. A relationship can contain genuine affection and meaningful connection while also developing dynamics that become increasingly harmful. This is one reason people can find themselves staying in situations that, from the outside, seem relatively straightforward to leave. Leaving is not simply a rational decision when attachment, hope, fear, familiarity and love are all involved.

Understanding these patterns does not mean that we should blame our past for our present relationships, or that every difficult relationship can be explained by childhood experiences. People change, circumstances differ, and relationships are shaped by two individuals rather than by one person's history alone. Psychological understanding is useful precisely because it allows for greater complexity. It helps us move beyond the idea that we are either choosing badly or simply being unlucky.

Perhaps the more useful question is not only “Why do I keep ending up in unhealthy relationships?”, but also “What happens to me when I become attached to someone?”

What do I begin to overlook? What becomes difficult for me to say? What am I afraid might happen if I assert myself? What do I find myself trying to prove, earn or repair? And, perhaps most importantly, what have I come to believe I need to accept in order to remain connected to someone?

These questions do not offer simple answers. But they can help us begin to recognise that relationship patterns are often about more than the people we choose. They are also about what feels familiar, what we fear losing, and the ways we have learned to maintain closeness with other people.

Sometimes the first step towards a different kind of relationship is not learning how to choose a better person. It is becoming more aware of what happens to us when we love someone.
