I can't find it, but it's been scientifically proven though that most women seek out the jerk initially as an evolutionary trait. There was an article I read that basically stated women seek out the alpha male to mate with and have a child with the best genes, of course, but then leave him and seek out a beta, because he's more stable and a more reliable father to her child. It really threw me for a loop that this kind of devious evolutionary psychology has been programmed into women since the dawn of time.
