I Do Not Want Ours To Be Separated

Hello, I am writing to you here because I want advice from you. My parents have been together for 19 years and they love each other a lot (obviously). They fight, of course, which is perfectly normal for a relationship, but the other day things didn't go according to the usual scenario. My mother was watching a match, together with my father and my mother she always lived a lot and started shouting, jumping, getting angry as if she would lose money if her favorite team fell. My father, on the other hand, no longer likes any of these teams and he didn't care who would fight, and after one of my mother's next demands, he said "These are for the stadium" and it became a scandal. Mom started yelling at him, scolding him, reproaching him. My father told her that he was shouting like a porter (which is somewhat true, because at times it is too much) and it became a crazy scandal out of nothing. And they didn't talk accordingly. The next day (ie yesterday) we noticed that all the photos they have together she put them in a closet specifically for photos. And when we were at dinner (my father was on a night shift) she would say the following things: "Obviously it's time for a change" "Apparently he wants to" "It was close today to send me to my grave", etc. I can't I found out how a mother could talk to her children like that and upset them. He was my father, if he wanted to leave and if he didn't love her, he would do it now. He says that for me, my sister and my mother are dying. I don't know what to do. If they separate, they will collapse. What should I do? P. s. A year ago, my mother sent her nude photos to a former colleague of hers, and she had a lover 10-11 years ago. P. p. 2 My mother scolded my father when he had Facebook because he was adding people from the village,
