Best Friend Problems?

I had this problem once. I just hung out with other friends without her...she soon got the picture. Especially when they break up and no one is there for her. I stopped being mad about the whole situation and let her lay in the bed of problems she had made. Soon she will be the one to come crawling back saying how much of an idiot she has been and if she ever acts like that again tell her. Idk it worked for me. Everyone is different! GOOD LUCK!
