why do i have to wait on his friends like a maid?

so my boyfriend has this thing where every friday his guys come over. and every time they do, i’m expected to make drinks, serve snacks, refill beers, all that. i try to grab a seat once they’re settled but he gives me this look like i’m being rude. last week i actually sat down for like two minutes and he pulled me aside and said “this is guy time, just let us talk” — but i wasnt even talking! i was just sitting there. i brought it up and he said “its just how it is when you’re the wife energy” even though we’re not married. tbh it makes me feel like the help, not his partner. and it’s weird because in bed he acts all romantic and says im his queen but then outside the bedroom i’m basically his servant when his friends are around. i dont even know if i can bring this up again without sounding petty. but it sucks. and his mom does the same thing with his dad’s friends so i think he just thinks this is normal?? idk. am i overreacting?
