i was r*ped by my ex and my bf resents me for it

basically title.

i used to live with my ex. last year we broke up but still lived together cs we were broke college students. i met my current bf this january. we started talking, some drama happened and i told him i was still living w my ex. he let me stay the night at his place all the time after that. there was this one night i went out w my friends and had a little too much to drink, but came back too late so my bf was asleep. with no where else to go, i went back to my place and blacked out. i woke up to him having sex and with me, but u was too drunk to push him off me. i left when i woke up and bawled on the sidewalk outside my bfs apartment.

fast forward two 2 weeks and I still hadn’t told my boyfriend. I was scared that he would blame me because so many people are like that and we had just started talking. At some point, I thought we went to the bar and I drank a few and I ended up telling him what happened that night. He got so upset and I remember him crying saying that he wished he was there for me.

ever since then, every time we ever get into a major argument, this topic somehow always comes up. He always brings up how useless he felt and today he said that he resented me for not telling him earlier because he couldn’t have done anything to help. I know this is the off my chest subreddit, but I’d like to know if anyone had any advice on this.
