number my dear, you must not beat yourself up over this, it is not a case of thinking you couldn't manage - it is out of the question. It sounds as if David needs round the clock nursing care on hand which is not possible at home without a live in nurse.
It is not hard for patients to get confused in hospital, they hear so much going on around them, so I would not worry too much if he has forgotten what was said. By "home" he may also have meant "out of this hospital"so again, don't let that fret you.
Wishing you both well. 
After Cataract op I understand I need sunglasses.
Are books a thing of the past ?
I've been caught on the hop. Come on in and make yourselves at home.
and (((hugs)))
