Am I AITAH for asking my daughter not to share any information about me with her father?

[u/Individual-Opinion49]

I have not spoken to my daughter's father in 20 years. I ended the relationship due to physical and emotional abuse (broken ribs, if I disagreed with anything he said he would pin me down and scream at me "Am I right" until I said yes). At one time I had a no contact order. We live in a small town and he is known to tell anyone that he wishes I was dead. He repeats this phrase to his daughter quite often. My daughter has discussed my personal business with him through the years- that I went back to school to become a doctor, that I got my black belt, etc. He rants that I ruined his life and that I will pay for doing so. I have respectfully asked my daughter not to say my name to her father or discuss any aspects of my life with him- yet she refuses to do so. He has not made any overt violent gestures towards me but I have a security system, a Glock and a personal protection German Shepard who pretty much goes everywhere with me. Am I over reacting and am I the ass hole for requesting that my achievements, locations, and other information not be shared with my ex-partner. She says her dad is wounded and is unhappy that he lives in poverty while I have created a good life for myself and he is just venting.

NTA. You are not overreacting. Why is your daughter allowed to see him after what he's done?
