My best friend, whom I've known for a long time, isn't talking to me. I don't even know what I did wrong. She hasn't been answering her phone when I call her. She hasn't been calling me back either. She hasn't answered ANY of my texts or emails. Our last phone conversation was in March so it's been a month of noncommunication with her. It's really bothering me because she's my best friend and I don't want our friendship to end, y'know? Now I don't even bother calling cuz I know she won't pick up. We don't go to the same school so we have to call, email, and text each other. But now she won't even answer me. It's really irritating. What should I do..?
