so i’m in halls in first year. in the first term i was in a friend group that didn’t work out, we ended up having to change housing plans for 2nd year. we talked things out back in december and there haven’t been any issues since then, although the dynamic of the flat and friend groups have changed. i share a kitchen with a few of the people i was in the old friend group with, and one of them is bothering me particularly. we used to be pretty good friends, we would often check up on each other, etc. now, he’s completely anti social and barely makes an effort to say hello. it’s kinda upsetting for me to share a kitchen with people who hardly make effort to be polite anymore. any advice for me?
