Don't feel that there is needs to be a rush to get him home instantly, rodmommy I am sure he will miss his wife being there so often, but making changes without careful thought would not be a good idea. Just keep visiting him as often as you can while you plan his future with him.
Are you quite sure that having him at home is the best thing for him? You say he has improved so much since he has been there. If he is at home, he will have the same carers that he had before, or else someone in the family will have to do all that they do, and more. It is a full-time job looking after someone who is incapacitated.
You don't say whether he is bedboind. If he is, then there is a LOT of work, some of it very physical. Even if he is up and about, he will need care and attention 24 hours a day, which he will be getting in the care home. Can you really provide that and go to work, have a social life yourself, get rest, without endangering your own health?
Consult the social work department, his GP, talk to others in the same position. There is such a demand for care home places that they may be helpful if it can be done practically. Only go ahead with this when you have considered all aspects.
