Just keep your eyes on your road. Does it change anything with your MR? Or does it change inside you? It´s about you first man. Control only yourself.
Set some boundaries, relax, don´t reveal sources if you confront her. Don´t use an accusatory stand. Just let her know that you know. By the way...what do you know?
This is a marathon. I know you have been running a long time so...
