Amy I'm not sure that moving back in is the best thing for him to do. I think it'd come across as forcefully as an ultimatum. Moving closer to home shows independence, a desire to be near his family but no so close he's watching/spying and trying to control them.
It'd be interesting to find out the real reasons for her wanting him to move out. Traveling for business is a rather lame excuse.
She wants the separation she should have been the one to leave, not him. If he has the right attitude, he can undo this. It's iffy though, because of the obvious emotions.
