Little this is all very scripted you know this. Have you read DB in awhile? H tells you he sees you happy to alleviate his own guilt of wanting to break up the family. You said the right thing by stating "I don't want this for our family" and by letting him do the work. I've followed your thread but you have to continue to detach and let him go.
It isn't over til its over L. My W dropped D word 2x a month for a year straight
Just get yourself in a place emotionally where you don't react. You keep melting down emotionally in front of him and you need to be strong.
Let him do the work but you do your homework in the background
