My best friend won't talk to me and won't tell me why. I've asked her and she still won't tell me. I don't know what else to do. I have apologized and tried to explain to her that I never did anything.

Perhaps there has just been a big misunderstanding. Write her a very nice letter. In it, ask her to explain to you what you have done to offend her. Perhaps something was misinterpreted in an e-mail or text? Also, in the letter, be apologetic for anything that you may have done to offend her. This doesn't mean you are taking blame, but that if something was misunderstood, then you apologize for that. If she is a true friend, she will come around. I know, this has happened to me more than once in my life.

This used to happen to me all the time when I was younger, one day my friend done it again and I just realised that she wasn't worth it an I made some new friends who I am still very close with and they are my true friends. Maybe you should do the same? Or if you really want to make friends with her then try to like make her laugh or something or maybe try talking to her when she's on her own. Hope this helped! X
