Oh Lucky what rotten luck to be ill on top of everything else. you poor thing.
But I do agree with others that this goes to show just how difficult it would be for you to be caring for your DH while he recovers. Please take up the offer of the room in the local home, just until your DH has recovered and is more mobile. Yes, the cost will be enormous, but I think the relief you will feel will more than compensate.
You can visit him daily, and know he's being cared for properly. And you'll be able to sleep at night. These past few weeks have been an absolute nightmare for you all, and you really need to be able to have some respite from it all.
Finally, Lucky, if you do opt for the room in the nursing home, please do not allow yourself to feel guilty about not going with your DH's first choice, because you must think of yourself too. Good luck
