There's really nothing you can do. The only tip I can give you is to not hope for your parents to get back together if they do get divorced. If you move on it will be easier for you and your parents. My father's been divorced twice, first time was my mom and second was my step-mom who treated me more like her child than my actual mom did. It's really just watching and waiting to see what happens. It sucks but you just have to deal with it.
