Remember David:
If what your doing isnt working, try something else. The definition of insanity is doing the same thing over and over and expecting new results.
If you were to move out or ask her to move out, it would be trying something different, Right???
Just a thought that may help in your decision. It may shake her/wake her a bit, and it may not. Dont worry about loosing her as you have already said she is gone in mind/spirit. So get your Motor running!!!
