Wow, y'all are so far apart on your terms that I can't imagine this being done without lawyers and a protracted legal battle! Good luck to you!
Regarding her moving back into the house, you're probably going to have to consult with a lawyer on that since the home ownership is tied up in the business. It's probably going to be messy trying to unravel what her stake (if any) is in the home and business. I'm sure her position will be that she has a stake in both though.
