Let her do her thing. Let her spread those lies and venomous remarks about you.

I believe that she is digging her own social grave. People are not stupid, you know.

If you believe you are in the right, (and I assume this because I don't know the other side of the story), then with time, you will become stronger. She is creating her own disaster waiting to happen, while you can just stand back away from her fire, and focus on the positive things in your life.

Nobody deserves a back-stabber in their life. Good riddance, is what I say.
