I know the internet is exactly the best place to be asking this kind of thing but you escapist types seem to be pretty intelligent and reasonable. Basically I have two main groups of friends which sort of overlap, the people in Group A are fine I have no problem with them but something is starting to bug me about the other guys, they're going on outings and various other friend type activities without inviting me, then telling me all about them afterwards and sometimes they're kind of vague when talking to me. Should I just not bother with them anymore and stick with who I consider to be my true friends?
