When my DH & I downsized we bought a Park Home (Mobile Home). We went from 4 double bedroom house to 2 bedroom. With our house we had a huge garden, our Park Home had a smaller but more manageable garden.
We could escape each other although it was not huge but as it had a kitchen/diner & a lounge we could have space & do our own thing.
Now I am widowed I'm in a 1 bedroom Park Home, no spare space at all but as it's only me I'm fine.
I would sit down with your wife & discuss why she doesn't want to move & try to discuss options.
