Just went no contact with abusive sister

One time my sister called me a bitch out of the blue and stormed out of a store. Then she left me stranded in a city I had never been to without money or a phone. I ended up alone in the rain sitting on a park bench for hours. Eventually I figured out how to navigate back to her apartment. I was supposed to stay with her for a few nights. She screamed at me and threw my things because she was upset about things from childhood. Her partner helped calm her down and allow me to stay the night because I had no where to go. I heard her in the other room screaming “I don’t want to live anymore”. The next morning we met for coffee and she started yelling at me in public.

She is really scary and mean. She has a long history of doing things like this to me. She’s belittled me, humiliated me, insulted me, and harassed me. When we’ve gone out to dinner she would text on her phone in the middle of me talking without any acknowledgment of what I was saying, as if I wasn’t there. She has a nasty glare she uses to put people down.

She’s insulted my looks, my intelligence, my life decisions.

I won’t pretend like I’m perfect. I’ve done things I regret. But she is entirely uncontrollable and unreasonable.

The most recent incident is she texted me and my wife in a group chat and told me I was a horrible sibling to our other sibling. She attacked me and said that my wife and I are “immature and unhinged” because of a situation related to a car accident and navigating our insurance claim. She made my wife cry. That was the last straw for me.

I just officially went no contact with her. Biggest relief in my life.
