I hate her.

Now, I don't say that lightly. I'm usually not one to express that. I have a lot of women friends, a loving mother and sister, etc. I have somewhat recently come to realize that not only do I hate my girlfriend of the past three years of being in a relationship, but that I also have come to realize that I hate the entire gender. The way they carry themselves, the way they act, the way they talk, literally everything. I also hate the fact that I have to pretend to not hate her so that our relationship can survive, because I know that if I express my true feelings towards her, she will leave me for another man and I'll lose everything. I'm so confused, depressed, and in a funk. I don't know what to do.
