Ignore your H crazy behavior. Write on the boards or read a book.
Maybe your C can recommend someone for you and your H to see together. Where you can establish what your new relationship means. I think you need to layout ahead of time what your expectations are and discuss these with a C as a moderator.
1. I understand how you feel right now, that you no longer want to be married but I want you to know that I am willing to work on our marriage and make changes in my own behavior, for our children and our relationship.
2. I will not stand in your way from you continuing on the path you are on.
3. When I start dating I do not want to introduce our kids to my new boyfriend until we are engaged or have been going out atleast 1 yr. (Best to put this one in terms like you will be dating - I told my H I didnt want our kids crawling into bed with me and another man but I was really refering to him and another woman)
4. If we are living as roommates the household chores should be divided as follows...
I think once you set up some parameters you can DB in the home with him there. He should have nights where he stays home with the kids and you should have nights when you go GAL. Spend money on yourself and getting new hobbies. Do cool stuff.
p.s. this is the opposite of my behavior when my H was still at home. I just filled our house with "how could yous???!!" till my face was blue. It didnt work.
Hang in there. You are doing great under extremely stressful circumstances
