Ugly truth

So me and my boyfriend met through his ex. They were in a relationship and he cheated on her with me. So as bad as it sounds I think karma is her to haunt me.. he believes all females are emotional creatures . Some stuff that is important to me is not important to him.. my questions are 1) am I wrong for feeling like I have to be perfect to be happy? 2) am I asking for too much when I ask him to stop talking to one certain female not because of anything he did but because she gives me bad bad vibes ?
