Hi,
I remember when my Mum got really ill and lost her mobility completely. It was an intense time and my Dad had been trying to cope with her mobility difficulties for a while before this. The fact was that it came down to safety for both him and my Mum. In the end, I went to our GP. I was there at 8.30 after the most horrendous of nights and I must have looked as exhausted as you feel. My Dad had finally admitted he couldn't do it anymore, had heeded the doc's warnings that he would be ill if he continued to try, so although it was one of the worst days of my life, that following day, my Mum was moved into a local hospital (she had a urine infection or she would have gone direct to a care home). From that point on, choices had to be made. My dad went through all the emotions of admitting he couldn't care for her anymore and he had to let her go to be cared for elsewhere. But, heed this. Now, she is safer, he is safer and has quality daily time with her, has support from the care home staff and he's much healthier. He isn't worrying the same, he doesn't have a bad back anymore (well, not often) and he's able to cope with the tasks he needs to.
It's one of the hardest choices in the world to let your man go to be cared for by someone else because you can't do it or, you can do it but at high risk to your own help. Remember, if you wreck yourself, he will end up somewhere else anyway and then have to walk that journey without you. I don't know if you are at this stage yet where you really can't cope anymore but it sounds like you are approaching it.
Please be brave and be strong and go and talk to your GP for your own sake and your man's. It all comes down to safety in the end and a care home isn't the end of life. To be honest, in my experience, it has provided another chapter for my Mum and Dad and me. She wouldn't have gone for days out with my Dad as he couldn't cope with her needs. The home has arranged these for him and I went too on some of them. Really, when the times comes, try to look at it as a good thing. You may not want him in a home and that also is OK but whatever your choice ... STAY SAFE!
Thinking of you and hope my words and experience help you a little.
With you,
