Rigby might not want to hang out with the other because:

Pops- He's not exactly fun to hang out with since he like those boring old stuff

Skips- Has a serious attitude and mostly spends his time in those candles and stuff for meditating I suppose

Benson- Has a serious attitude and doesn't see Rigby eye to eye

Muscleman and Fives- THEY are fun to hang out with but Muscleman's My Mom Jokes and they are just secondary friends to Rigby
