What should a person do/ How should a person react when his/her parents are divorcing?

hola guys, a litle help here! See, my parents have been over HUGE anger parades lately, and today, my mother just called me and told me she was gonna divorce due to cheating of my dad...O.0...My parents haven't signed any paper yet to setle the divorce but they are furious t each other, they used to have ordinary couple fights but now they are really serious...At this point I really don't think they'll change their minds, my mother has already hired a lawyer and my dad will probably get one soon aswell....

So what do tu think is the proper way to react to this? And what do tu think I (or ny person facing this probleme) should do?
