Plain and simple. For women its not the actions of the guy that defines him but his looks and level of attraction women have for him.

Odds are that the "nice guy" a woman you know hates is just an unattractive dude who had the audacity to expose his romantic feelings.

But guess what? If that guy was just chill and laid back he would also have been perceived as a weirdo and would have been ignored as well.

The biggest players I are also the biggest "nice guys" when it comes to interacting with women. But guess what? they are the ones to walk out with the girl at the end of the night. You don't see him get labeled as "nice guy" after walking out on a girl after his post-nut clarity.
