Ok so I have a this friend... and she is my best friend. We have been friends for 15 years. We are pretty much sisters and love each lover like sisters would. But she is prettier than me and has always had the luck with guys that I have never had. We used to tell each other everything and we were real close. About a year ago one of her boyfriends broke up with her and so she cut her wrists and took meds and overdosed. She was in the hospital for a while. A couple months later she told me that it was all my fault for the overdose. I consider myself a good friend espically to her, she has made wrong decisions and can be rude and inconsiterate a lot. I have never put her down, discouraged her, or hurt her as a best friend. If anything over these 15 almost 16, years she has hurt me. We made promises not to have sex until we were married, we made those promises to each other. She recently got mad at me when I went to the beach with another friend instead of her. She has her ways to be controlling and hateful and very self centered. I have considered myself to have always been in her shadows. She went to the beach and found some guy and had sex with him. It didn't surprise me but I was extremely disappointed. She talks to him and I don't like him too much, but I have my reasons. She treats me like dirt when she is talking to him, or anyone else. She gets angry because I have other friends and she has had to switch schools because she lost all her friends because of the way she treated them. I just don't know what to do about the situation. People tell me to stop being friends with her but you can't just leave a friend you have had for 15 years. ANY ADVICE??
