My mother has always been controlling. If she didn't get her way she was rude and hateful towards a person. She has always been independent even though she has been legally blind. She's a fighter, has overcome many major health problems. Now she is 92+ loosing strength in her legs due to arthritis. She depends Heavily on my 93+ yo father. He has dementia, terrible arthritis and is hard of hearing. She can be quite abusive to my father due to his hearing. He always gives into her and does whatever she wants. He drives still. We tried to have a caregiver to live in but my mother was hateful, rude, refused help and told us to get rid of her. The house was clean, they were clean, they ate well, health improved! What can you do with someone like that? Do you just leave them alone again like they want until something terrible happens? Has anyone dealt with someone like this and how did you deal with it?
