rape?..

So back in FEB, I met up with one of my old, close friends. I knew he wanted sex but I told him that I didn't want to because I just got out of a relationship. The next time I met with him, we were both laying down and next thing I know he's pulling on my pants and I'm telling him to stop and he's so much stronger than me and he gets hem off and starts giving me head and in trying to get him off of me. Once he got off, I got off of the bed to pull up my pants but before I could, he slipped himself inside of me and I'm constantly telling him to stop and he wouldn't. He finished and I immediately started crying but not in front of him. My abdominal hurts so much, I was so uncomfortable. I was confused as to why he did it. I thought maybe he liked me or wanted to be with me. The next time I saw him the same thing happened, but I got him to actually stop and he got upset so I left. Now, I am back with my ex and he has no idea of this and I have a guilty conscience cause I feel like I betrayed him. I don't know what I should do. Someone please help. Was this in fact rape?
