Why would you have to pay your h to move out? I understand that you may be under water on the house, but I don't see how you would be forced to pay him. Have you thought about asking the court to force a sale of the house and dividing/selling assets to pay off the mortgage? I can't remember what you've written about that.
I understand about having your own timeline for moving. It sounds like you and your attorney have it figured out. I'm glad that you have friends and family supporting you while you transition.
