Is it normal for my kids to fight all the time?

well I don’t know. I’ve always had a messed up family. when I was 2 my parents divorced. my mom married my step dad when I was 10 and my dad married my step mom when I was 7. every other weekend I’d go to my dads house. my dad and my stepmom NEVER fought. they were like perfect for each other. but my mom and step dad, they fought EVERY SINGLE DAY (no exaggeration) FOR ABOUT AN HOUR. and like my step dad set my house on fire and then when my mom called the fire department he yelled at my mom for calling the fire department because hes the biggest jerk in the world. I hate my step dad. now its gotten to the point I ignore him all the time and my mom says how much she hates him but she wont divorce him because that would mean that we’d have to move back to this slummy place where I used to live where some people consider it a “ghetto” and my mom doesn’t want that. so practically the only reason that got married in the first place was so I could move where I am now. ahh. and where I live now all my friends have the perfect parents and whenever they come over my house they get really scared because my step dad likes to rip a door off its hinges all the time when he gets mad and smear dust all over the white walls (im not even joking) then he complains about how me and my sister are such horrible kids when I get straight A’s and dont do drugs like other kids in my neighborhood. and then he complains about my mom and I want to seriosuly kill him. omg sorry im going on and on but I really hate him. well anyway yeah my friends aren’t used to the atmosphere and their parents are perfect so yeah not every family is like that. and for your other question, I try not to talk back to my mom. because my mom has to deal with enough already. :)
