My best friend might be ignoring me?

I would talk to her about what she is doing to you that pisses you off. If she doesn't respect how you feel then she isn't worth it, but it is always worth a try to take her aside and tell her. She won't figure it out if she is pissing you off any other way and if you keep it under wraps for awhile it just becomes a bigger issue. If you tell her what is going on, and she goes on acting the same way then she isn't worth the time.
