Hi, my brother and I have never gotten along, and mom's health problems and dementia have aggravated things. She fabricates things that pushes his buttons, and she does the same to me. This time, I fell for what she was saying, and confronted him through email about it. He sent a rancorous response full of accusations. It appears that we are going to be unable to communicate about mom's difficulties. Any suggestions about how to handle these kids of interactions?
