Don't ignore her. Try your hardest to be yourself. I'm struggling with that now. You are going to walk on eggshells around her for a while. The fastest you can just become yourself the better. Cadet put Sandi 37 rules and read detachment with love.
When it comes to detaching it needs to be with love, not cold, spiteful, revengeful, or mean. One way to go about this is to treat WW like a neighbor.
So, you still speak, hi and bye. Hope you have a good day. And go about your way. If she wants to talk listen and validate. You don't want a hostile house. So being kind will help with that.
