Conventional wisdom for dealing with a bully is to respond in kind.
I agree with this line of thinking. All the soothing in the world is not going to make a dent in his issues. He is in serious need of IC. And as one simple girlfriend to another, get the F*ck out before he breaks you even more. I can just picture you like Mojo, saying a year from now, why the heck did I stay so long? Sometimes we can't see the brutal truth until we remove ourselves from the line of fire. Maybe this is not in line with DB principles but I really don't believe any of that approach would work with your M. Get yourself some good legal counsel. This whole thread is just painful to read. I'm sorry you are suffering so much. LFL
