I don’t like it when my dad is home

I just want to rant pl don’t hate or anything.

Yeah it may seem weird. Whatever I have today, the life I have is because of him. He gave us everything and I’m really grateful for it. Butttt I have seen my parents marriage. It’s not that good. I mean we don’t always have a gloomy atmosphere at home. But they argue a lot. I was 3-4 years when I saw him hitting mom with a broom but I couldn’t even understand what was happening. Then in 6th grade, he beat mom with an umbrella till her leg started bleeding. I was so scared and just froze I couldn’t even do anything. My brother came and stopped him. When my 10th boards were 2-3 months away, they had a terrible fight. It literally reached till divorce. My mom’s side relatives came and un dono ko Samjhaya. Their fights began in November 23 and continued till June 24. Like can u imagine? I studied so hard the entire year I was sure if scaring 90+. But I only scored 86. I was so disappointed. Abhi bhi jhagde chalu hi hote hai. He curses mom a lot. I can’t bear it now. Mere papa thode se Ghusse waale hai. His parents didn’t give him enough love idk much what happened. I mean he’s good and bad both. Once we went to our grandparents house (dad’s side) and dadi was taunting mom. She started crying and dad saw it and said chalo hum ghar jaa rahe hai. Three years ago he got transferred to another city due to his job. He comes home during the weekend. Sometimes he stays for a week and I don’t like it cause ik some argument between them is gonna happen. I mean he’s good father. He wasn’t that great till 5th. But recently he’s showering me a lot of love. My mom and brother say papa tujhe kitna pyaar karte hai. Our relatives also know that. But… it’s different. I saw him torturing mom a lot.
TLDR- dad is thode se angry type and my parents argue a lot which I hate
