is anyone really close with their boyfriends roommates?

i’ve been dating my boyfriend for a few months now and i typically spend 5 nights a week at his house. he lives with one guy and a couple. i get along with all of his roommates. the other night my boyfriend and i were cuddling on the couch and his other roommate came up and said,“aww i don’t wanna be left out”and laid on top of me. i buy them food all the time and they pay me back or buy me food too. we also have couple movie nights a lot and we just watch movies all night together. my boyfriend thinks it’s weird how great we get along. does anyone else get along with their boyfriends roommates? or is it weird lol
