It was the difficulty with mobility that forced us into a decision about putting Mum into a Care Home. We had carers coming in before that and although we had slipped into some sort of a routine, it was blooming hard work. Carers visiting 4 times a day is ok but what they can do is limited, their timings are often not suitable to you unless you employ them directly yourself. However, your husband will be in the place he knows. A word of advice though, if Social Services or the hospital discharge team think you or your family will help out with care, they will rely on that as much as they can and you will get less help. Stand your ground. Do not allow your husband to come home until everything is in place with as much outside carer help as you can get.
Also, how do you feel about wiping his bottom, clearing up after accidents, etc? Some people can, some can't. It isn't about love, it is about people's strengths. I can, my sister can't. She can do other things though that I can't.
If you decide on the Care Home route, please make you sure you visit plenty to be be sure you get the right place. There is one thing that makes you feel worse than putting someone in a care home and that is when that placement breaks down. If you visit plenty, from the corporate type to the independent type, you will get a feel for what you are looking for. The hospital cannot force you put your husband somewhere you are not happy. Once again, Stand Your Ground. They will try to bully you because that is their job. A lot of hospitals have an agency who will help you find a home but I found that the CQC site was the biggest help as they have all the latest reports on how effective the homes are.
Finally, if your husband's care needs are medical, you might qualify for Continuing Health Care. Have a look at the "Care to be Different" website. If you qualify, there will be no fees to pay but it is a bit of a fight to get it. If you do not have a lot of savings, and the only home you have is the one you are living in, then you do not pay the full fees either.
There are many support groups out there so make sure you take good advice from them as to the way to proceed. Don't rely of Social Services to do their best for you or the hospital. They are bound by financial constraints so they work to their budgets.
