There's nothing wrong with asking someone to leave if their gaming style doesn't mesh with yours. It doesn't mean they're not your friend. It doesn't mean you can't socialise outside the game. Not doing one activity together is not the end of a relationship; unless that's the ONLY thing the relationship was based on, in which case it wasn't much of a relationship to start with.
It's not like everyone in a gaming group is joined at the hip. You Are Allowed to do stuff in each other's absence.
