Most Helpful Girl
Chances are these dudes aren't really assholes.
Any ex most girl has, she will see as an asshole because it didn't work out. My own sister dated the guys who really were "nice guys", but every time they broke up, she made them out to be pieces of shit and exaggerated everything. A lot of girls do this after breakups to help ease the pain of their relationship failure. These guys are likely normal ass dudes.
However, women don't like dicks specifically, they just don't like asskissers or pushovers. Like any guy, we like guys who have multidimensional personalities. We want a guy who can be sweet but hold his own, challenge us mentally and even correct us on our bullshit mistakes and help us grow. A lot of nice guys passively sit around, wait for things to happen and do nothing but try to appeal to us by nodding their heads with a soft "yes ma'am."
You gotta find the balance, man.4THIS IS NOT RELEVANT ANYMORE

I have replied to this question before (just formulated a bit different) but I'll do it again.
When women date an asshole I think it's because they've made a mistake. Most people that are assholes will obviously try to hide that and it won't show until you get to know the person a lot better. Women are humans too, they make mistakes.
As far as the "women don't date nice guys" idea, I don't think that's true either. I'm a nice guy and I have no problem finding women. BUT women don't want a pussy and they definitely don't want someone who pretends to be a nice guy just to get close to them. If you're genuinely a nice guy that will show and likewise if you're not. And as for the first problem, if you act like one of her girlfriends you will obviously be treated as "just" a friend (Personally I don't think a friend is "just" anything and some of my best friends are women).
Now, if you're being friend zoned, don't see that as a problem, see it as an opportunity to learn more about what women likes and wants... just remember to be yourself with women, if you pretend to be someone you're not any relationship will crash and burn as soon as you start being yourself again (and nobody can keep up a charade indefinitely).
Anyway, those are my thoughts and ideas about the subject. Good luck with finding the right girl for you! ☺0THIS IS NOT RELEVANT ANYMORE
