my boyfriend said he hates girls and now I feel like she’s trying to break up with me.

I got a boyfriend a few months ago and she was my first ever real girlfriend. We started dating a month ago, and for the last 3 months we've been together. She loves me and says she loves me, and I love her. But I have no idea if I should be mad at her or if I should just say it. I don't know why I hate girls so much and it's a weird feeling. Like it’s like if I was mad at a friend or something I wouldn’t even get mad. Like I get mad at people, but it’s not like it would affect my relationship or my friendship.
