I would all it more your forever hell, and it is exit falls into Dante's Inferno.

After watching and reading about your "fun" (ha no way), I think you should give him his wish.

You own custody 100% and he is a money pump and nothing more. Why? He is acting like a child, and no child can be a parent.

I think you can officially call it. You are done, and if desires a maelstrom of a house, he can go get an apartment and move out, and custody arrangements based on your needs wins.
