Hanging out wuth his friends every weekend!

Almost every weekend my partner wants/plans to hangout with his friends! I get invited but sometimes it can be draining, id rather spend sometime with him at home doing something. I don’t love his friends its two of his guy friends & the girlfriends of them, one girl is sweet the other one is a big immature little flirt I don’t like ger as much as she doesn’t care to act a certain way in-front of other girls boyfriends! (That makes the time spent with then unpleasant) well im more of a homebody! & yeah is fine to hangout with then once in a while but i feel like he never says no to them! I don’t make plans one weekend w my friends so that we can have a relaxing weekend for once & there goes again pops an invitation of his friends & by the next i either plan one with my friends or the same thing Will hapoen (him making plans) & seems like we never get to stay just at home & relax. Being social drains me, i can go on a few weeks or more not seeing my friends & im fine… but him 😮‍💨😮‍💨😮‍💨
