Wow. Your H really does meet the definition of someone wanting to have their cake and eat it, doesn't he?

I'm not surprised you're moving towards more distance from him. And I am so glad you are not feeling fear. You are absolutely correct that you shouldn't' agree to any settlement without having a L look over it. You supported him, made a home for him and raised his children. I don't know what the law is like in your area, but here, you'd be entitled to half of all assets and pensions as a starting point, perhaps more if you are housing minor children, and child maintenance until the youngest is of age. I know your son is older. And it seems your H is meeting his financial responsibilities right now. But it seems to me you'd be more secure financially if you were divorced and that's going to come as a nasty shock to him.
