Oh Syl! - this is so moving!
Well, they call it the long goodbye, don't they? Remembering my mother, I must have said goodbye to her (the real her) years before she died. I understand in part what you are going through, but it was my mother who had dementia, not my spouse!
I have read that your vacation has been cancelled - I hope the accident/illness is not too serious. I'll pm you later.
As for your poem - it reads perfect to me - well chosen words!
Hugs
