had sex but he doesn’t remember

This is my first time making one of these because i’m so confused right now. I (F20) slept with one of my acquaintances (M20) while we were at an apartment party. We had sex and everything was fine except me being a bit embarrassed. Come to find out that he doesn’t remember having sex with me due to him being on a 3 day bender. He says he was blacked out. But we were having full conversations all night he didn’t seem any more fucked up than the rest of us. We ended up in a bed together cuddling, he starts kissing me and i tell him we can’t because i’ve slept with one of his friends before. But he insists so i folded which i was okay with. We end up going to the bathroom where i ask him if he is feeling happy and consensual to which he says “yes i have been wanting to do this for a while” i was also on my period and told him this he said he didn’t care. While we were fucking the condom broke and i asked him if he wanted to keep going and he said yes. I just found out that he has been telling my friends he doesn’t remember anything and that i rapped him. I’ve messaged him asking him if he is okay and we’re this is coming from but he won’t answer i just don’t know what to do.
