Sounds like a lot of Drama. When people try and inject drama into my life for no reason I just distance myself, cause I dont want it.
Half my family did nothing but cause drama in my life, so I havent talked to them in four years now. I dont DESERVE it because I never created stupid strife for them. If they want to waste their lives living out 'events' that they manufacture thats fine.
Moral of the story, cut all communication and let her rot. You'll obviously never change the way she feels, and she'll just make you more angry.
Life isnt supposed to be about that kinda shit.
