You are in a spot that we never, ever thought we would be in. I admire your strength in handling it the "right" way.
I don't know what else to add. Just to stay focused on your kids and being a role model to them. Show them how to be strong and how to behave with dignity and respect even though they know that mom is wrong. IDK, let them be mad at her. Don't defend her to them other than letting them know she still loves them, too.
Anyway, hang in there. You have a lot of people here pulling for you and offering our support. Let it out here as much as you need to and let your W see only that you are "fine" with it. You are ready to move on and deserve better.
