Mum was treated for cancer, first we went the come home 'I'll manage'...meaning me...A few months later she had to have an operation, and I insisted she went into a home. They said Mum was doing well, but I was near a breakdown - I never had a day or even an hour off, never saw my husband or children, ended up cooking because she wouldn't eat the meals supplied.
It was hard seeing her in a home, but it got to the point that my health had to take priority. Sadly after an unnoticed infection, Mum died 2 months later, and almost 4 years later my health is almost back to normal...
Think about your health...carers are mostly great people, but occasionally they just don't turn up, or do as expected, leaving you to do it. I don't know you, but I would recommend a home - after a few weeks you won't need to visit daily as he'll make connections there x Good luck
