Am I overreacting if I want my mom F42 to leave my dad F45 after seeing chats with multiple women on his phone?

My parents have been married for 18 years, but there’s literally no spark or love left. My had has such bad temper and frequent use of abusive language make things difficult. When I was a kid, they fought a lot, and sometimes it escalated to my dad breaking or throwing things, slapping my mom, and even calling my nani to talk about divorce even though he was at fault.

He’s been living in a different city for work for the past five years and never calls or texts my mom more than twice a month. He has no interest in her life, like what she likes or buys her anything. My mom pays for everything using her salary. He’s also used abusive and harsh language on me after I scored a bad (95 percentile in JEE) and to the main point, he never shared his phone password and always used to chat with middle-aged women from countries like the Philippines, Malaysia, and so on.

Right now, him and my mom aren’t speaking, despite my mom being so kind and good. She has to face this, and I can’t take it. I just hate him. I have no good memories with him. He doesn’t care about me like a dad should. He just always talks about studying, college, and career, like yes, that’s important, but I don’t want anything to do with someone who has used bad words for my mom, doesn’t love her, and chats with other women.he casually uses such bad words and has called me haramzadi madarchod after jee result and he says it was one time thing so its okay…and mind you I have heard these words countless times in their previous fights like ughhhh he Is just an unpleasant person and I cant be myself freely at all around him

Today, I literally caught him translating some “miss you, love you” texts to the Philippines and sending them. Like, what’s the point of staying in such a dead marriage? I really want to cut all ties with him. So, people, am I being wrong or overreacting?would not any woman want a  divorce ???
