AITA for not having any contact with my parents and brother after constantly violating and ignoring my boundaries and safety?

I(27F) have been struggling with whether I’m being unfair or if my reaction is justified.

In October, my brother(21M), who has a diagnosed mental illness, stopped taking his medication and came to stay with me. His condition quickly escalated: he wasn’t sleeping, was incoherent, and behaving irrationally. On the night of October 3rd, while I was asleep, he entered my bedroom naked and tried to get into my bed, saying he wanted to hug me. I was terrified and called the police. Although the police initially said they couldn’t act because he seemed “adequate,” they later took him voluntarily to a psychiatric clinic. He was released shortly afterward despite my attempts to explain the situation. Later that morning, he followed me home and threatened to break into my apartment if I didn’t open the door. That evening, police detained him again after he became aggressive in public and fought with officers. This time, he was involuntarily admitted to a psychiatric clinic by court order. After this, my mother came to stay with me, originally for a week, to visit my brother. I made it very clear I didn’t want to be involved in anything related to him. Despite this, I was repeatedly pressured to help with logistics, translation, phone calls, and emotional support. Her stay was extended without my consent to a month.

Around New Year’ Eve, my father visited me and my husband on his own initiative (we didn’t invite him). I initially thought this was an attempt to make peace, but instead he was openly hostile toward my husband from the start. Whenever my husband wasn’t around, my father repeatedly accused him of being manipulative and of “tricking” me into marriage, despite the fact that I proposed first and the timeline was entirely my decision. Throughout the visit, my father also kept pressuring me to contact my brother, even though I had clearly stated months earlier that I did not want to be pushed into any involvement and that continuing to do so would lead me to cut contact. I let it slide at the time because he was a guest. The breaking point came when he woke me up at 7 a.m., pounding on our bedroom door for no emergency reason, just to hand me a written “life plan” he had made for me. This plan involved me returning to my home country, preferably without my husband, abandoning my education and career, working under my father, and living under my parents’ control. He spent the entire day pushing this plan and dismissing my actual goals until I finally snapped.

After that, my parents continued a pattern of extreme panic and control: repeatedly catastrophizing minor external events, demanding immediate responses at all hours (including the middle of the night), and threatening to come to me if I didn’t reply fast enough. When I said that I was not responsible for managing their anxiety, my father demanded instant responses whenever he texted. That was it, and I cut the contact.

AITA for cutting contact after all? What should I do?
