Is it normal to feel this way in every relationship?
I seem to have some serious commitment issues in every romantic relationship I'm in. The past three relationships I've been in I get sick of them after about three months, and so I end them. I'm 21 and have never been in a long term relationship. I want to be in a healthy relationship though.
I've tried to think about what could be the cause of this problem. The only thing I could think of was that my father was kind of abusive to me and my siblings when we were children. When I was about 5 or 6, he put a pillow over my face and tried to smother me and he would hit us with his belt to punish us. This seemed to be a possible answer to explain my aversion to commitment. But my sister doesn't have the same relationship problems.
So I just wanted to know if this was normal? And could this be a logical explanation for why I have this problem?
