Are women "prone" to repeating past mistakes?

A few weeks ago, I was engaging in a conversation with my dad about women in relationships, and he said that, "Women stick to patterns, and go back to the same men over and over again." When I say patterns, I don't mean abusive relationships where women do not leave their significant others. I mean situations where women repeatedly like the same type of guy that is never right for them or women keep "hooking up" with the same guy that will never want more than free fun.

So why is it that women do this? I get the simple explanation: Women are weak and overly emotional, so they must return to their past hookup buddies hoping they have changed. But, I'm not buying that excuse because it's based on a lot of stereotypical bullshit about women. I have a couple of other possible explanations: Maybe women feel comfortable with these types of men and don't know who might be a better fit for them. I think relationships among 20-somethings have become so devalued in college culture. Maybe women think that's the best they can get, so they settle for hookups. I also think some women repeat past mistakes while others learn from them, so I think it's a grand generalization to say that all women are trapped in their past relationship mistakes. 

Just some thoughts on a rainy Monday night (a.k.a I don't want to do my take home exam or write my papers)
