<human>: I have been with my boyfriend for 6 months and very early on he expressed that he wanted us to be living together. We are not living together, but he is moving in with a friend [19? M] I do not know very well, who we will call Stephen. 

My boyfriend has been absolutely lovely to me throughout this relationship, I thought he was a lot different to other guys. 

He messaged me telling me that he told Stephen that he should expect moaning when he moves in and I come over. We are sexually active, but I didn't expect it from my boyfriend. I told him that I was surprised by what he said, then he said that Stephen started the conversation. I said that he still said what he said and I got 'whatever' as a response. 

I am confused. I didn't say I was mad. I feel as though I can't talk to him after his 'whatever' response. 

I am a very private person. I mean there's nothing wrong with having sex but I don't think I would tell close friends what he told Stephen.
