I had to put my mother into a care home as she has dementia. We have not spoken to my brother for over 20 years. I contacted him and he went to see her. She didn’t recognise him and the carer said he was heartbroken. She then said maybe she will know you next time to which he replied, "There won’t be a next time. I won’t be back. It’s too upsetting seeing her like that." I sent him a message telling him I’m here for him and he replied thank you. I’m heartbroken for him as she still recognises me. What should I do now?
