Where do commitment issues stem from?
We all know someone who has trouble with commitment. You know the type—the serial dater, the person who suddenly stops calling or showing up when the relationship starts to progress. It can be frustrating for both sides.
Insecure Attachment
There are a few reasons why a person might struggle with commitment. They may have formed an insecure attachment/avoidant relationship style. This type of personality style usually stems from a person’s childhood and their relationship with their parents or primary caregiver. Likely, as children, they felt as if their emotional needs were not being met and have since learned to not give as much weight to their emotions making it harder to get close to people. People with this type of attachment style tend to enjoy being in relationships but become uncomfortable when relationships get too emotionally close.
Another reason why someone might struggle with commitment is because of catastrophic thinking. They have severe anxiety about relationships and always think the worst— “it will never work out, why bother,” “I am going to be trapped,” “I am just going to get my heart broken,” etc. This usually stems from childhood experiences of seeing their own parents unhappy and arguing on a regular basis. Or, they may have had a series of bad relationships in the past that has led them to think nothing will ever work out. They have lost faith in relationships and are fearful of getting too attached.
It is, of course, difficult for both sides of the relationship when commitment troubles are a factor, but it doesn’t mean it is not possible to find love and to have true, meaningful relationships. It just might take some work. Meeting with a licensed mental health professional can help those struggling with commitment to identify the reasons why they might have trouble in this area and what can be done to move forward.
