Liz,
Rob sounds much more at peace, I am planning a visit to our local hospice shortly (just to 'see' at this point)but have been so pleased when nurses said everything is done for pain-relief and maximum comfort. I've also spoken to the husband of a lady who went home for quite a while after she'd been 'stabilised' and made more comfortable there--so whatever, and wherever, you should both be as well looked after as is possible at this awful time.
Thoughts and prayers remain with you, you're a lovely and strong woman Liz and will be a great source of support for Rob and his family---and we're all here for you
