Am I a bad daughter if I cut my parents off financially for enabling bad behavior from my older brothers towards me?

Long story short, dad went to my older brother and spoke horrible things about me. As a result, there was a verbal altercation between my brother and I…it was so bad that he probably would’ve assaulted me if it wasn’t out in a public street. After it happened, my father tried to apologize and said he spoke bad about me because the alcohol made him do so. Anyways, I was beyond devastated and kept to myself. That argument wasn’t just about what my father said…my brother also ran his mouth talking horribly about my parents. Anyways, it was too much for me to process so I cut him off and don’t Olán on mending anything with him. However, I recently found out that my parents have kept contact with him this entire time despite what happened. No apologies were said…nothing. Meanwhile, I’m out here this entire time paying my parents truck payment every month and wasting money on them like an idiot. I asked my mom if it was true that she kept contact with him despite his horrible behavior and she lied to me by saying no but I had evidence that she lied to me.
