why do i have such bad commitment issues? only child thing? single parent thing? i hate kissing.?

I'm a girl. I hate kissing but I like having sex. Could it be because I don't have a dad? I have a really hard time being in relationships. I usually break up with whatever guy it happens to be after a month. Even the really great ones. What is wrong with me?

I don't like it when I feel like someone loves me too much. I like being liked and even loved but once it reaches a certain level I freak out. Please help. Thanks
