There's nothing you can do. If your parents are getting divorced, it's probably for the best. You need to know that it's not your fault and that even though your parents are getting divorced, they still love you. Your friends and family will always be there for you. Be wary though, divorced does bring out the worst in people. I know because my parents got divorced when I was six. Ignore the starfishs like dkamm65, Toasty_Engineer, and com4de. You'll pull through.
Just keep your head up. Everything will get better. Trust me.
