What I would do if I were in control of this situation would be let her parents take care of her and order all sorts of rehab and therapy for her that might be helpful. I'd give them 6 months to a year to see if there is any improvement. Then I would re-evaluate her condition. After this long, one more year shouldn't matter to her husband and may make a world of difference to her.

At least give her a fighting chance to improve.
