I have been in your shoes. In my opinion, the only way she may come to her senses is that she realizes what SHE lost. I would absolutely take the high road with the kids, but I would not let her see you sweat right now. Take the lead on the next steps regarding the Living situation, Money, Arrangements with Kids, etc. Once she realizes you are not going to be her punching bag, she may come to the realization of what she may lose. In other words, the best defense, is a good offense right now. Best wishes!
