Hey, my parents are legally separated at the moment. I get what you are going through.
They probably are discussing what they are going to do with you. Divorce has some extra problems when it comes to the kid, because both parents tend to want custody. I know my dad does. They probably are also discussing things like who you visit over the weekend, where your stuff goes, car dropoff when you need it, etc etc.
It’s not weird to be worried, but I promise there is nothing to worry about. I doubt they are discussing anything related to you that’s bad.
