Do men really prefer bitches?

I think that men prefer bitches, women who treat them like shit and who aren't interested in that man...but instead of keeping away, this man jhust continues pursuing that woman. It's sad because this man will never see the woman beside him who really cares for him. I am that girl...so I start ti understand that I have to change and behave like a bitch with this man..maybe then he will notice that I am the woman to marry?! I don't know. How to change from a nice woman who knows what she wants, but doesn't like to treat people like shit...to a woman who steps over people jhust to get what she wants without taking care of other people's feelings...I don't know :-(((
