I can relate to this very well. My parents divorced my 8th grade year, and it wasn't pretty at all. To the point of my mom using my sisters phone to text insulting messages to my dad. I kind of saw it coming really, they were always fighting.
The way I dealt with it was just playing a lot of video games. Seems cliche, but that's what helped me, and I often listened to the Skyrim soundtrack, it just calmed me down. My dad also had us signed up for family therapy, which I kind of thought was a bit too much, but it helped a little bit. In hindsight, I realize I kind of closed myself out from most things socially, which I definitely advise you to not do. It'll drive you crazy a bit depending on how affected you are by this.
Some other stuff happened between my parents that I don't feel the need to type about, none of them good. But for the most part, my advice is to try to be independent. Your parents might try to do stuff to convince you to be with them, or at least your mom most likely will, and they might let their ego get in the way and do stuff to spite the other. Do your best not to pay attention to their relationship too much and just focus on yourself, like school and/or work. The stuff between my parents made me upset for awhile, and made me lose focus on school, causing my grades to drop a bit. Still passed, but yeah, still not good.
Hope you'll be able to pull through this, and good luck to you, man.
