Well asking what you should do is a very open ended question. To me, I might ask why you feel as if you need to do anything? Do you think your parent's shouldn't get divorced? Are you perhaps wondering how you can comfort your parents through this?
But I mean, unless there is something you'd like to do or that you should do, there's no real need for you to feel like you have to do something.
Due to the explained situation along with the question, it's very safe to assume that I have mixed feelings about this. It's only natural for a human being to want to do something about it.
It's never easy when someone has made a decision that permanently effects our daily lives. We tend to wonder if it was our responsibility. If we should've done anything differently.
If you're unsure how to feel, you might want to confront each parent directly with your questions. It might not make you happier, but hearing an explanation will help inform your opinions. Even if you take it with a grain of salt.
