Well, I have to comment I understand how the meanness can cut so deeply. I want to say that I also get it how NC is sometimes the only way not to be hurt. I liken my H sometimes to a charging bull and I'm wearing red. The only thing to do is get OUT OF THE WAY.
I respect the need to protect yourself from hurts. I have struggled with how DB doesn't really address the abusive spouse all that much.
Perhaps now is not the time to be communicating with him. Only you know that. Maybe it's time to GAL not for a reaction, but purely to start making yourself happy. Taking care of yourself right now seems like the most critical step. Take care.
