Lack of a social life
Maybe he doesn’t seem to have a social life. You ask what he’s doing on any given weekend and…he’s not doing anything. You never hear of him spending time with friends. Maybe he has one “best friend” who he sees…twice a year. Be wary of the man who has no social life. He might expect you to be his entire social life. Men are generally less skilled at cultivating close friendships than women are, but your date should at least have some friends he sees every month. If things get serious and he has no friends, you’ll always feel guilty going to do your own thing.
