MC, I think you handled that well. You were able to get everything off your chest and let her know how you feel. I think we have to do that for our own sake. Most of the time it goes in one ear and out the other, but I think you got her to thinking.
Now is the time to go dark. You have to realize you can't change her. Just take care of yourself and the boys. Limit talk to only about the boys. Keep conversations short. Do not call her unless absolutely necessary, only about the boys. It sounds as if you have the boys most of the time so that shouldn't be a problem.
