Death of my father - Day 34 and my abused sister

has opened up a can of worms. My younger sister has been abused for years from her alcoholic husband. He is not worthy of the word more like barbarian. Today, we are talking about the the inheritance from Dad and she turned on me. She has been drinking beer to go to sleep, She works graveyard, massive sleep deprivation. The barbarian calls her up whenever he wants and has no respect for her or her time. She turned on me today and told me I was just like him. I have decided not to talk to her anymore. She is whacked out big time. That hurt me a lot. I will not help her anymore ONLY if she asks for it.
