So we've been friends for about 3 years, she's great and we're very close (not to say if she was awful to me I wouldn't cut her off, but keeping the friendship is a priority).
She's been with her boyfriend for about 6 months, not very long but theyve gotten close quickly. She has a history of awful boyfriends and he is by far the best so I definitely approve of him as her boyfriend.
The issue comes in where he is just kind of a dick to me. I'm very much a mean jokes/banter kind of person and I've made sure to tell him that I mean it light heartedly, he seemed ok and has playfully been mean to me so it was all good. But recently hes been taking it too far (eg, I'll call him an asshole and he'll start bashing my weight or how I'm lonely because im single) and been doing things that make me uncomfortable (slamming the speed in the car constantly knowing it makes me anxious).
On the 30th we went out for a sort of NYE celebration since a few of us would be working NYE so couldn't then. I've talked explicitly that being overly coupley and lovey in front of me makes me uncomfortable. You dont have to pretend not to be dating, but don't constantly be kissing and cuddling. But that night they were all over eachother and so I sort of avoided them to avoid the third-wheel situations. I just stuck with our other friends.
When we stopped for food, her boyfriend started kinda randomly bashing me for being uncomfortable with their PDA, calling me bitter that they're in love and im lonely (lol). He also made a comment about how im fat and probably wouldnt share my fries with him, when hed already had a full burger + fries meal and had ordered more food (again, lol). He then went on a bit more, trying to apologise with mostly "Im sorry youre bitter youre alone and jealous we're in love"
I'd like to clarify that I had mostly ignored him, even when he started bashing me, and i only actually had a go at him when he started fake apologising. I wasnt even having my usual banter with him because I just wanted to ignore him.
Throughout this, my bsf was either ignoring it or actively comforting him.
I want to give everyone a bit of grace since we had drank a bit, we were definitely sobering up but not sober at all. But I very much believe drunk words are sober thoughts, so I absolutely do not want to talk to this guy again.
What I wanna know is, how can I sorta nicely say "youre boyfriend is an utter asshole and I dont wanna be around him again" without damaging my friendship with my bsf? is that even possible? Thank you
(fyi, British so we can drink at 20)
TLDR; Bsf's boyfriend is a asshole to me (bashing my weight and me being single), how can I nicely say I don't wanna be around him anymore without damaging my friendship?
