Do you have any help coming in @Long journey ahead . I wonder if getting someone to sit with your husband while you go out for a mooch round the shops, coffee with friends, the gym or whatever you'd like to do would give you a chance to have some life of your own. It would also get your husband used to the idea of other people helping him. As things progress he may well need more help with day to day tasks. Age UK have a Help at Home service. It's not in all areas but if it does run in yours in might be a start. Its not in all areas and they don't do personal care. I've also heard (from @canary) that TuVida do a similar service.
I've done a search for other threads on Korsakoff and these are the results I came up with. I hope some of those will have some information you find useful.
