You were 4 hours late. That's a waste of her time waiting, favor or not. I'd be pissed too. This is not a sign of bipolar. It's a sign you are unorganized and think you're above being on time somewhere. You seem to want a lot of recognition for these favors you do. Maybe you're so late because you don't really want to be doing them. Maybe you're passive aggressive that she's married when you want her. I suggest some counseling for yourself.
