Mil has fell 9 times in the past year this last time she broke her ankle, this is the same ankle she broke some years ago which is why she is immobile, she ended up at the nursing home for therapy for about 8 weeks and convinced the nursing home she was ready to go home, she wasn't, she was home 2 days and fell and sprained the same ankle again! She has been back at the nursing home for a couple weeks and is refusing to stay when therapy is over, we are all at a loss here and don't want her to go home it's too dangerous. She has been begging for my husband and I to move in with her but that is not possible it just won't work out, she is a very demanding woman and I know it will cause us problems, we are all so stressed over this and my husband is just sick about trying to get her to stay, any help?
Years later my hubby understands how stressful and difficult that would have been. At the time he was all for me staying home and running my life around his father. As it ended, we got in home care for him (they were lousy, sadly) and I wound up going out to his place 2-3 times a day to care for him. It was a better choice than having him move in.
If your MIL can possibly afford some in home caregivers, try that route. Be aware that once she begins the constant falling---her options are going to be very limited. And the "compliance" when she's in the NH is totally normal. My mother will sing and dance for anybody who is coming to her house to give her therapy, then she sits down and doesn't move for days.
Your hubby's guilt is normal---but help him be strong.
