The issues that remain are hers. The circus she is in will implode.
Do what you need to do for you.
I copied this from one of your posts a while back. Someday I will use it as a FB status. I think it applies:
"I may not be someone's first choice, but I am a great choice. I may not be rich but I am valuable. I don't pretend to be someone I'm not, because I'm good at being me. I might not be proud of some of the things I've done in the past, but I am proud of who I am today. I may not be perfect but I don't need to be. Take me as I am, or watch me as I walk away."
Forget this drama; spend the next few days focusing on your son. Enable him to be at the appointed place at or before the appointed time.
