I hate my mom

My parents are splitting up, and GOD am I happy. They are like oil and water, they are constantly fighting. While my dad is super pushy and can't understand the word "no", my mom has terrible anger issues were sometimes she won't talk to anyone for days. As you can see these traits don't go well hand in hand. I thought they would be able to have some breathing room and peace now that they dont live together anymore, but the fighting has just gotten worse. My mom is constantly trying to brainwash my brother and I to get us to hate my dad. For example, my dad and I took a cruise together while my mom and brother went to Canada over the summer. When they got back my brother refused to even look my dad in the eyes. He was a totally different person. I just don't know what to do anymore. My mom is super irrational. She constantly believes the worst in everyone, and uses this to create webs of lies. For example my dad took us to see a house yesterday that was also my mom's dream house. And I just suggested she go and check it out, and she just goes off in a rampage about how it is rude to try to pick where she lives. We just have a super toxic relationship. She is so mad that my dad divorced her, and yet she was the one who was constantly complaining about him for years and pitting us against him. she's just like a child and is mad because she didn't have the last word. I'm only 13 so I cant move out of the house. Keep in mind my mom is taking anger medication and is seeing a therapist. I've also started seeing one.

Advice???!!
