Rape?

I hook up with one of my coworkers. We were always couple like. Last night we had a get together. He was being very mean to me. I got very drunk. All my friends left and it was him and I and he told me to come into the room. He laid me on the bed and said I’m taking advantage of you. I said okay. I’ve been crying all morning. I feel violated. I have no idea if it’s considered rape. Please help.
