Based on what you just said, no go on the MC. He is looking an easy way out. I would not give it to him. If he wants a divorce don't stand in his way but by no means help him get it, and I would pretty much express that. Something like: "I understand you want a divorce, it's not what I want and it's not whats best for our child but I wont stand in your way. I also will not help you leave your family, so I'm sorry but I simply cannot got to counseling with you to help dissolve our marriage." or something to that effect.

As for leaving the marital home, NO WAY! he wants to leave, then he needs to leave. All of it. Don't do anything that makes you look like you are going along with his destructive behavior. But remember to act calmly with everything. Set firm boundaries and calmly and lovingly (As best as possible) hold them.

I know this is so hard, but you got this.
