is there a "boo! hiss!" button? What an egotistical S.O.B.!I'm not sure if this applies in your case, but I know a couple who seemingly got along OK until the woman started down the tragic Alzheimer's path. Then the guy got very angry because she was not there to magically turn stuff in the refrigerator into meals, magically turn dirty dishes into clean ones, magically cause bills to be paid and so forth. He literally had no idea how to push a button on a microwave and complains to friends that there is no food in the house. He now wants a divorce thinking that the "magic" has gone out of his marriage.
I feel sorry for her, having put up with that nonsense all her life, and now finding her abilities being destroyed by a horrible disease, and him not knowing how to care for her, or even care for himself.
