Mom won't let dad touch her. She has been separated for more than 20 years. Why?

You must be at least 20 years old, and you are an adult. One of the couples always puts up with it for the sake of the children. Maybe my father did something when he was young, and my mother was heartbroken. For the sake of children, she has a happy family and can only live without patience. To open mom's heart knot, let mom and dad get back together, and to solve neighbors, you need to tie up neighbors, and there can be no overnight worries between husband and wife.
