I would tell her that when she is behaving like a child to stay away from me. I wouldn't want to be confrontational either, but I could only take so much. I'm not sure if this helps you, but this is what I would do. You know just recently I meet this girl who has a personality disorder, I had to stop hanging out with her. She has a drinking problem really bad, and she would get very upset with me for trying to help her. One time I gave her a tv, and she got really upset with me because I asked her if she wanted me to help her carry it. She also let me watch one of her movies, and she got upset with me because I said the movie was good, and not great. I was just thinking to myself if your going to get mad at me everytime you see me what the sense of being friends.
