I sympathise with you so much, I had sort of the same situation with a very close relative, she was being scammed at home, I was too far away to look after her and I made the decision to bring her to a care home near me. I felt so guilty putting her in there, hated the idea, so did she I think, although she never complained. Anyway, now two months later she loves it, she wishes she had done it earlier, and I can see her as often as I want. I know your OH is not well but you will still be able to be with him as much as you want, but the one thing is you will sleep at night and get your rest, which you need. His life will not be over, just different, but he will be cared for. Do it, you will not regret it, and just make sure you are there for him as much as you can be. Sending loads of good wishes for you both xx
