Raped by my boyfriend of 3 years

My boyfriend and I had been out with some friends before coming home and going to bed. Sometime during the night I felt like something was on top of me weighing me down and I woke up He was inside of me on the verge of finishing. I was so scared I couldn’t get up and he wasn’t listening to me say get off of me what are you doing. He finished and then rolled over and went to bed I remember not know what to do and not wanting to move out in case he tried to hurt me in some other way. In the morning he acted like nothing had happened and he was acting just like he always did and when I asked him why he did what he did the night before he told me that he hadn’t done anything wrong that I was his girlfriend and that was what happened in relationships
