Please tell me what's wrong with me and my dates?

recently I realized I'm attracted to girls who tries to dump me after a few dates. I mean after a few dates with someone when she wants to dump me ,then I try to make her change her mind and afterward I dump her after some other dates! when is someone is nice to me I kinda loose my interest to her, I sound like a lunatic bastard who freaks myself out as well. tell me please what's wring with me? how can I solve it?
