Feeling awful after a hook up

So, my boyfriend and I went through this giant break up about 2 years ago for a couple months. It wasn’t my idea. I was a mess.

I tried to forget about him/get back at him/move on, so I invited this guy I was talking to online over. I was fully into the idea of a one night stand and he fully knew what he was coming over to do.

Fast forward to him showing up at my house and I instantly felt my heart drop and didn’t want to go through with it, but I did because I felt way to awkward to say no. How do you say no when YOU invited him over?

Throughout it I kind of checked out and stared blankly at the wall while he did his thing. It was the worst feeling having someone on top of you that you didn’t, but you couldn’t verbally say so because you felt like you owed it to them.

Anyway, my point is, has anyone been through something similar? How did you feel after? Does it still bother you?

I know I didn’t say no, I don’t blame him at all, I just still feel gross that I even invited him over. I felt so unclean for a week after🤮
