Friend put me in a sexually uncomfortable situation UPDATE

So about a year ago, my guy friend stayed over, and I’ll skip to what happened. He essentially pinned my arms above my head while I was in bed, I was telling him to get off me, but he didn’t, he then got under the covers and tried touching me (I wasn’t wearing any trousers). He was originally sleeping on the sofa, but decided to go out for a smoke and came into my room on the way.

I made it so very clear that I didn’t want him on top of me, but I had to scream to get him off me. We haven’t really spoke much since. And I’ve also heard that he’s done similar, if not worse things to other girls.

He’s reached out to me, but I haven’t responded, so he sent me an arsey message, saying ‘I could be dead for all you care’. I feel strangely bad for ignoring him, but why should I?

Sometimes I feel like I’m overreacting and maybe he was just messing around, but the truth is, that isn’t the first time he’s put me in a situation that made me feel uncomfortable and vulnerable.

UPDATE:

So my friend who’s a mutual friend of ours invited me and my son over for a roast dinner today, the guy who put me in the awkward position text me saying ‘are you going to be around ______’s today with Noah? I have a cold so will steer clear if that’s the case as I don’t want to pass it on’ I text back saying ‘yes Noah will be there’ so we get there for 2, and about 15 minutes later the guy shows up. I’m fucking gobsmacked. Why?!?! It makes no sense to me, he acts like everything’s fine, but I don’t, I get up and leave, and in the process ended up in tears. WHY AM I SO EMOTIONAL ABOUT THIS?! I feel so stupid for creating a scene, but I felt sick being in the same room with him. I don’t want to tell our mutual friends, as I don’t want to create drama, but now theyre so confused.
