Whew, that was a lot! You must be exhausted. I feel your pain, really, almost physically, when I read it. So much of it is similar to what my H says.
The deal with giving you the house - what does he mean? Transfer it to you in your name? If so, he has no right to come in anymore.
Now there are people who are able to work together for the kids so they rebuild their house into a duplex. However, the separate living spaces are separate and private. It still gives the kids a feeling of one home and having all their stuff in one place.
A lot to digest there... But it sounds like you handled it very well, considering.
