I have this friend. We've only been friends for about two years. We became like best friends. Earlier this year, she started making new friends and trying to make me best friends with them too, but we just didn't.. idk... connect, i guess. She became really close with those friends and she found out some stuff about them, and it made her really mad. They didn't actually do anything to her, but it was immoral, and she decided that she hated them. She called me and wanted to talk about them with me and I just wasn't really interested, so I didn't react. She started telling me how boring I was, and then started telling me that none of it was true. And I thought that it wasn't true,(it doesn't really matter what I think because as far as I know it's just gossip and none of my business) so she started telling me how I never believe her. so I told her how I have no reason to, since she always lies to me to keep her life interesting(and I have proof). She got really mad at me then and just hung up on me. I'm not really interested in being friends with her anymore, since she's just being a bad influence on me. Am I doing the right thing?

It sounds like you'd just be wasting your time on her. Ever thought she is just trying to find some acceptence? I'm not saying what she did was ok, just a thought.
