My fiance takes care of his mother & step father full time whom I believe both have dementia (but is un-diagnosed). It is obvious to me that he is burnt out, but he seems to refuse to do anything about it. He refuses to put his mother in a home, I have made suggestions for him to get help and a diagnosis, but he says he doesn't have time to go get help & his mother doesn't want any body else to help her. It would be fine, but he is very angry most of the time, yelling at his mother & step father about the smallest things & when I am over there it is very uncomfortable & highly stressful for me. The last time I was witness to this, I spoke up and told him to stop yelling. I just cant sit by & do nothing, it is borderline abuse. His mother is only 68, this could go on for a long time. She can't move one side of her body & can't be left alone.
