Really? Who does she think she is????

Who does my sister think she is? I have supported her like a child pretty much since 2006 and she has met some ghetto fab guy and thinks she can talk to me however she wants? She had the audacity to text me last night and tell me I was a selfish bitch and she never wanted to talk to me again, which is fine with me. Then, she said i was a horrible friend to her, this coming from the same mouth of the person who had an affair with my current husband!! I mean is she retarded? I have always stood by her and been a good friend to her. Not only did she have an affair with my husband, she called him and made up a lie that I was having an affair on him. Which was a total lie, she was trying to start shit. I talked to her ex husband yesterday and told him a few things about her and now she is pissed...Well, how does it feel you nasty whore? I guess you get what you give in life. I have no other siblings so I have always felt like she was my only friend. I have realized she is no friend to me. She is the biggest screw up I have ever met in my life. She is 26 and dates a 48 year old black man. Why? You ask. Because no one else will have her. When she is thru with him she Will be calling because she has no where to live, no car, and no job. Hell, he doesn't even have a home they live in hotels...lol   What a loser. Another thing my Mother can kiss my butt, because she defends my sister about the affair with my husband and participates in my sisters messed up life. She calls my sisters about 3 times a day and calls me about 1 time a month. She always defends my sister and if I call my mom to talk to her about my sister my mom calls and tells her like a 16 year old would. My mom acts like she wants to make my sister like her by acting like a friend to her instead of a mother to her. I'm just exhausted dealing with them. They act like pure trash and its embarrassing. I think I am going to wash my hands of the entire group. What do you think? I will keep everyone updated.
