I'm so sorry you are in this very difficult situation vannesser, and you Casbow.
My husband has been very reluctant to go out over the last few years, and even if he came in the car he didn't want to get out, although this was complicated by his mobility problems. Now he doesn't even want to go out to the garden. I think he just feels safe in his own little world. He doesn't like to have carers come in and refuses help with personal care but will accept someone popping in to make him a drink or something to eat. Because he isn't able to move around he isn't in danger of falling, or doing something dangerous, and he has enough cognitive ability to know I am out and will be back before too long. I think Kjn's suggestion of having someone come in to do some 'cleaning' while keeping an eye on him is a very good one. Hopefully if you can get someone skilled in working with people with dementia they will be able to build up a relationship with him.
I worry that you will not be able to carry on if you don't get some kind of break. It's hard to have to be doing things on your own, but it would make you feel better.
Sending you a big hug.
