My wife of fifty years wont be coming home

My partner has had a progressive dementia for some years now, and it isnt the vacant eyes, smiling at everything type. Its the nasty Scottish Glasgow fishwife, who flies off the handle at nothing type. Until now I have managed her, with a little help from my long suffering daughter (Why is it a mother always dotes on the son, when the daughter puts in all the effort?)
Anyway. My wife had to enter hospital for surgery on a hernia she has had for a long time, but ignored. And the successful surgery meant a stay in hospital that has exposed the worst in her, which we have been covering. Full details will not be given here. But she is being "managed" until she is healed enough to be transfered to a home with secure dementia care. I can no longer look after and be safe myself..
And the most horrible part of this is the relief I feel..Its a really $h*tty way for a wonderful partnership to end..😞
