In most US laws, if you are given a gift, and are married, it belongs to husband and wife. If you split, you have to split the gift. So, the house would be appraised, and any equity would be split equally. If one wants to stay in the house, they would pay the one who leaves.
So don't be so quick to decide you have nothing. Also, does your son Love being a JW? At age 8, I would have jumped ship in a heartbeat!!! I hated going to meetings.
I have a friend that got divorced, remained ok with her former spouse, for the sake of the child. She moved to a near by town, and bought a house. It was better for the ex-husband, because that was where his work was. They finally decided for financial, and for the sake of the child, for him to just rent a room from her, and logistically it was better for both of them. They have done this for 10 years.
