I hosted a party at my house a little while ago and when the party had wound down, me and my friend (casual friend, not super close) were hanging out having a drunken conversation. After a while, I had said I was tired and going to bed. This was around 5 am. He then continued to carry on a conversation which I had tried to end several times when I repeated myself again, saying I was tired and wanted to go to bed. I then followed up asking how he was getting home. He said he was driving so I offered to grab him a blanket and pass out on the rug since all the couches were taken. He ignored my question and continued to talk. I then told him I could call him a ride home and pick him up in the morning to grab his car which he also seemed to not hear. I tried bringing this up several more times until I finally started raising my voice and telling him to make up his mind and asking him if he could hear me. He seemed to ignore everything I said and kept trying to drum up more conversation. It ended up with me telling him to get out 45 minutes later (around 5;45 am) and (semi)forcibly escorting him to the door. He's usually a really good guy and I like hanging out with him, but I'm embarrassed to talk to him now. Am I the asshole for kicking him out?
