Your friend seems to have some problems going on and it seems obvious by the way she is acting and not handling it very well. It was good that you stayed away from her as well. I think that your friend should be left alone for now until the problems are over and or can be solved. And from what you said about her not wanting to get you involved, it's safe to say that if she ever accuses you of not being there for you. Tell her what happened and you know what? She shouldn't treat her friends like that though. If you guys are speaking terms again though, I hope you guys can talk/work it out again. Otherwise, I'm sorry to hear about this. I wish you the best of luck as I got nothing else unless there is anything else I might of missed.
