My boyfriend has Sunday video game nights with his friends (we're all men) and play like Mario Kart and stuff.

I'm not a huge video gamer, but I like playing from time to time.

His friends aren't particularly nice to me, they make uncomfortable jokes at my expense (nothing evil, just rude) and I don't like them much but my boyfriend doesn't have many friends and has a difficult time making them.

On this Sunday, I joined in, but left to get dinner out of the oven and when I came back I asked casually to my boyfriend "did you miss me" to which one of his friends replied "we didn't even notice, just ignored you and kept playing haha"

I sort of brushed this off, but then after a while someone says "we didn't think you wanted to play anyway" which doesn't make sense to me because why would I be playing if I didn't? But from past events, I gather it was a sarcastic "well you suck anyway so it doesn't matter" kind of thing. (which is true I guess)

Anyway, I said "this is getting awkward, I'm going to get my work ready for Monday" and left the room to do my own thing and they finished and he came into bed asking if I was okay and I said I was fine (half-true, feeling a bit shitty but not end of the world), but that I think his friends are nasty and that they don't like me around and it's best I just do my own thing on Sundays.

It means a lot for him for everyone to be together and get along,  and really important outlet for him. But I'm just really tired of his friends and do want to play games with him in a group because it can be fun when they're not making snide comments, but I don't want to listen to their snide crap. He has talked to them about it before, but it hasn't changed.

Am I the asshole for telling him his only friends are assholes and being sulky over it and taking myself out of his only real social outlet when it matters much more to him?
