Even after a romantic relationship ends, many people find it difficult to cut off contact with a former boyfriend or girlfriend. The love may have broken down, and the deep affection or sense of entitlement that once existed may no longer be present, yet the search for each other does not always stop. Friendship can remain intact. The question is why so many people cannot break the thread of communication even after the storm of separation, and what psychology lies behind the “ex but friends” relationship.
A report in the psychological journal Psychology Today highlights four main reasons, drawing on several studies, including research from the University of Kansas. It suggests that some people stay friends with ex-partners for emotional relief, some out of necessity, and some because of old love that has not completely faded. The reasons are not always romantic. They can be practical, emotional, social or a mixture of several factors.
One reason is old trust and mental comfort. When two people are in a relationship, trust is built between them. They develop the habit of speaking their mind, supporting each other in times of trouble, and talking when one of them is upset. Even after a breakup, that habit does not disappear easily. Many people therefore remain friends with an ex-partner because talking to them feels comfortable. They can still share personal thoughts, and they are with someone they already know well. This kind of friendship can be good if both people respect each other and accept the new state of the relationship. It can provide continuity and emotional support without the demands of a romantic partnership.
Another reason is contact due to necessity. Friendship with an ex-partner is not always based on love or emotion. Sometimes it is simply necessary to keep in touch. The two people may have the same friends. They may share assets, pets or children. Some may also receive financial or other benefits from their ex-partner. Research has shown that friendships formed solely out of necessity often do not last long. However, such contact can maintain a good relationship between the two, especially when practical matters require cooperation. In these cases, the friendship is less about affection and more about managing shared responsibilities and social connections.
A third reason is friendship to avoid trouble. After a breakup, many people do not want to get into new fights or arguments. They therefore talk politely with their ex-partner, keep in touch and act friendly. Some people think that stopping direct communication can hurt the other person. Others worry that hanging out with the same friends could become uncomfortable if they are not on speaking terms. For these reasons, they maintain a friendship. However, friendships formed just to avoid trouble often do not last long. They can be fragile because they are based on avoidance rather than genuine connection.
The fourth reason is that there is still love left. Even after a breakup, love does not disappear from everyone’s heart. Some people still want to get their ex back, so they continue to communicate in the name of friendship. They hold on to the hope that one day the relationship will be okay again. Some do not want to see their ex with someone else. As a result, even if the old relationship has ended, they cannot leave the friendship. However, if one person only wants friendship and the other hopes to return to love, the relationship can create new problems. The mismatch in expectations can lead to further hurt and confusion.
Being friends with an ex does not necessarily mean that the old love will return. In some cases, friendship can continue even after the feeling of love has diminished. On the other hand, some people break up without bitterness, and it is possible to maintain a normal relationship between them. The outcome depends on the individuals, their history and their current expectations. According to research cited in the Psychology Today report, about 60 percent of people are friends with at least one ex-boyfriend or girlfriend. About 20 percent are friends with multiple exes. The report also said that LGBTQ people were more likely to maintain friendships after a breakup than heterosexuals. These figures show that staying friends with an ex is common, though the quality and meaning of those friendships vary widely.
The most important factor when it comes to staying friends with an ex is whether both people want the same thing. If one person wants to forget the old relationship and move on, while the other still hopes to get back together, the friendship can become difficult for both of them. Honest communication about expectations, boundaries and feelings is therefore essential. When both people accept the end of the romantic relationship and genuinely value each other as friends, the connection can be healthy and supportive. When one person is secretly waiting for a reunion, the friendship may become a source of ongoing pain. The psychology of “ex but friends” is therefore not a single phenomenon but a range of arrangements shaped by trust, necessity, avoidance and lingering love. Understanding which of these forces is at work can help people decide whether the friendship is helping them move forward or holding them back.
