I feel guilty

So my freshman year of high school I went with my boyfriend and his family to the beach. My mom let me because we were all sleeping in one camper and there was literally no room to do anything. I don’t think we were even dating for like three months at the time but our anniversary was while we were at the beach. He asked me if I wanted to have sex and I wasn’t really ready for it because one, I wasn’t even sixteen yet and two I didn’t really know him that well. So when it was the day of our anniversary I just wanted to go for a stroll on the beach. So before we did so I got a milkshake. So I asked him to watch over it while I used the bathroom before we left. When I can back I finished it and I realized I was getting groggy. So I wanted to go back to the camper. He said ok and carried me. I passed out along the way. I don’t know how long I was out for but I woke up on the bathroom floor. I didn’t see it completely clearly, but he was flushing something down the toilet. I realized that I didn’t have any clothes on, but before I could do anything I passed out again. I woke up earlier that morning and I felt really bad pain in my lower area. It wasn’t time for my period, but later that day I started bleeding. I feel like he rapped me. When I asked him about it he always said it never happened but I asked his mom when we got back and she said she was asleep and she didn’t remember.

I’m a junior now and I still get pretty haunted by it. I’ve been having dreams about it recently and I wake up crying. I’ve never really told anyone except my boyfriend that I’m with right now and my mom. I never wanted to report the guy because I was scared people were going to say that it was just my imagination. But I have really been needing some support lately.
