Posting this from a throwaway. My boyfriend is 29 and I am 27. We were showering together the other night when he asked me if I’d let him bring another person to our bedroom.

I laughed, thinking he was joking. I said, maybe Josh (Josh is one of his friends, I have no attraction to him and had no interest in a threesome, I just wanted to see my bf’s response). My bf said obviously not with another guy, but with another girl, maybe someone we’re both friends with, and we can ask them.

So I said what girls do we both know? Emily? (jokingly) and he said or Sophia? and I said or Maddy? (I still kind of thought he was joking). And then he said, or Ava? she’s legal now (she’s my sister’s friend – I changed the names tho).

One time recently, Ava was over my place with my sister and they were using a volleyball outside, and my bf was out there teaching them, as he’s done before, because he’s really good. Ava had just recently turned 17.

Ok now I thought even if he’s joking this is really weird and if he’s not this is disgusting. I stared at him. I froze. I muttered out what?? and he said he was just saying girls we both knew, not that serious. He wasn’t looking at me. I started getting angry. Ava?? She still has braces. You think it’s a joke? Or are you being serious?? You f*cking creep?? I said. And he said it’s not that serious and its not like he’s actually been thinking about it with her and to calm down. And suddenly I felt exposed around him and got my towel and went to the bedroom.

He took some time in there. When he came out and got dressed I had some time to think. I told him we’re done. He looked surprised. I told him to get out. I broke up with him on the spot. he said I was throwing out our relationship over something small but I told him to get out. AITA??
