As you write this stuff I can't quite understand it...mainly how she won't leave the house. And it's always that..."I can't leave the house.", not, "I can't leave you or the kids." Is that what she loves, the house? If you and the kids went away for awhile, would it bother her as long as she was at home? Is her preference for you to move away and leave her the home?
The "house" is next door to the neighbors. 'nuff said.
