HOW DO I PROVE TO MY BF I NEVER CHEATED ON HIM?

I would be really angry that he would believe her over me. If you really did nothing wrong and didn't cheat I would turn it all around on him. I would stop calling and texting or even trying. I would make it known that I didn't cheat and if he couldn't trust and believe me then I would be over it and him....at least make him think so. He'll eventually come back I'm sure. But that wouldn't be okay with me.
