Should I talk to my sister?

Well let me start by sayin that I always been taking care of my sister since I started dancin. She would watch my daughter and I would look out for her. When I had got enough money I bought a three bedroom house and I asked her If she would like to move with me. I seen it as she can be my built in babysitter. @ first everything was cool but then she started acting like I was her dude she be like buy me this and that and mind you she has two sons thats livin with us . When i go shopping I would get them stuff but she acted like I had to. All in all I was payin all the bills takin care of the house. One day she came home tipsy from a barbacue and my daughter was layin in her bed. She came down stairs sayin I dont want nobody in my room. I was like whateva then she got loud and started to be in my face cursing so I slapped her and then we started to fight like bitches in the street. She broke all my furniture scratched me put bite marks on me. So i called the cops and they wasnt going to do nothing. So I called my mom and she took her away. Buy ever since august of last year I havent talked to her and everyone keeps tellin me I should but I cant see my self being friends and acting like that **** didnt happen. Plus she ran my name in the dirt all around the neighborhood. Let me know what you think. What would you do?
