Im confused

Sorry this is nsfw but Idk where to post this so it's going here

I hooked up with my work friend a day ago.. It was me, him and a bunch of other friends/whoever and we were all drinking and talking etc. Anyway I don't think any of that context rlly matters because the main thing is the sort of accidental, drunk, hookup. I feel like trash because #1 omg that was not supposed to happen. I like him and we're kinda friends I guess but now I feel so awkward and uncomfortable when I think about it/him. It makes me so uncomfy 😩

Also.. after it happened neither of us said anything. He just cuddled me for a while and I was falling asleep when he got up pretty suddenly and went into his bathroom (we were at his apartment) his sudden movement woke me up all the way and istg I heard him crying. I just stayed there bc ik he thought I was asleep and he was obviously trying not to let me hear. Even if he wasn't I still would feel weird walking in on someone crying especially since we aren't super close or anything. like I wouldn't know what to say or do and I feel like I'd be intruding. I stayed awake and like 15 or 20 minutes later he came back (I pretended to still be sleeping) and cuddled up to me again. I was awake for a few more minutes and then fell asleep and I'm guessing he did too...... the morning was painful ofc. Lots of awkward laughing 🥲 we joked a little so Ig he doesn't completely hate me..

Why was he crying???? Did I literally make him cry?? Should I ask him about that or never ever bring it up? I have never been so confused or concerned in my whole life. Btw I don't know if his personality matters or anything but he seems to be a very shy, sensitive person so.. did I do something? Or say something? Am I overthinking this?? I don't think I did anything but then again he was sobbing in his bathroom so what do I know 😶 I feel bad now. I want to melt
