Why do some nice guys end up marrying some real bitches?

I never could figure that one out. Makes no sense at all, but I think deep down some men like being bossed around like they were with their mother. Maybe it makes them feel needed to have a mother figure in their life, but that's just not right. I guess some just like drama in their life. Seems like insecurities on their part. Perhaps that's a twisted version of love, to some.
