Tell your parents, you're but a child.

He is a serious dick!!! No wonder your parents made you break up with him, probably saw through him. I'd honestly do nothing, rumors are bound to float around but they can drift off pretty fast too because new drama is always going to start, and although some people will believe it, a lot of other people won't. If you try to do anything it will draw even more attention, just act like nothing happened and if anyone brings it up either ignore it or say "I never did that. You really can't believe rumors THAT easily, can you?" (just ignore it).
