I myself was always attracted to the sweet quiet guys, but I have noticed that a lot of women are attracted to jerks. For instance, two of my good friends have both put up with so much crap from their boyfriends. Every time they get cheated on, they swear they won't take the guy back, and next thing you know, BOOM! their back together. This goes on and on, and they keep taking it! They seem to focus on the very few "good times" and forget about all the bad times. A guy friend of mine is the same way. His girl friend (ex at the moment ) has broken their engagement atleast 4 times, and goes out with other guys, yet he always wants her back. I just don't get it. They seem to get off on the abuse. Or worse, they think they deserve it.
So it does seem to be true, girls ( and sometimes guys ) prefer jerks. Sad, but seems to be true. But for all those nice guys out there, don't think you need to be a jerk to get a girl, there still are many women who prefer the good guys. You just have to search for them!
