<human>: Went out drinking with my boyfriend and bestfriend. When we came home we were having sex and he said my (female) bestfriend's name. Our names sound nothing alike. Very early in the night he had made an overt sexual joke about her which I'd found a bit unsettling but I just laughed it off, not wanting to be that jealous girlfriend. He is really friendly with her and has told me how awesome he thinks she is. But he has acted the same way and said the same thing about another close friend of mine. We've been going out for four months. I really care about him and I don't want to end this relationship. I've never felt so intensely about anyone before in my life. He was extremely apologetic. He says he wasn't thinking about her and doesn't think about her like that. Is it really possible it was an innocent mistake? How likely is it? Does anyone have any advice on how I/we can get past this? 

I'm recovering from depression and have self esteem issues I'm actively working on with a psychologist (who just went on holiday for a month - fantastic timing). I don't know if maybe this is leading to me overreacting somewhat.

<bot>: Boyfriend said my bestfriend's name during sex. Is it possible it was just a mistake and didn't mean anything more? How can I get past this?
