Friendship

I just discovered/realized in the past few days that a friend who I thought was unaware of the shitty things that she does might just be a shitty person for selfish reasons, and I'm 90% sure that she doesn't really consider me a friend.  I always try to veer away from just demonizing people and turning them into villains because it makes me feel better, but...a lot of stuff makes more sense this way.  It was sort of an epiphany that I had while talking to someone else about her.  I hate this stupid feeling that I have now.  Also, this has me feeling slightly sorry for her husband, who I can't stand, and that just pisses me off.
