Dad is having an affair and may divorce his mother. As a son, how can I dissuade him?

I've been in this situation, so have my parents, but I'm not divorced yet. When will the original couple get along? You should learn to grow up and stop talking so childish. Be clear and powerful, persuade your mother to forgive your father and persuade him to come back to your mother, otherwise you will run away from home and scare your father. He was very concerned about you when he left. If I were you, I would have killed the third party, but it didn't work. I don't advise you to do this as a person. This is illegal. I was young once, and you were the only one who touched your father's heart the most. I must support the whole family tactfully. That's how I came. Good luck.
