I'm having the same conversation with my mum nearly every day atm, she feels so guilty because she's doing this but she just can't cope anymore, my dad has got so much worse over the last year.
She's very worried because the one thing he still knows is that he wants to have my mum around.
She's unsure how to handle it - take him there and stay with him a lot initally, or keep away? What will make it easier for him to settle in?
