He shouldn't insist, though, you don't have to be friends with those guys if you don't want to.
i agree with that, i wouldn't make him hang out with anyone of my friends that will make him physically uncomfortable. I mean i become noticeably uncomfortable, agitated and withdrawn around them...
but he's worth it so i may still go therapy even after letting him know.
he always says after we leave "are you ok?" and i always say something to the effect of "look, these just aren't my kind of people..." and then it happens all over again the next night... i say no, you go hang with them, really, id rather not. he insists and i join knowing full well what its going to do to me
