AITAH for cutting off my family after learning what happened when my dad reached out to them?

A few years ago, I (f29)got a call from my uncle Brody(m48ish) that my father had committed sewerslide. It was a rough few days for me, but brody's brother (my other uncle m48ish) said he promised my dad he would take care of everything. A week after the incident, I go over to Brody's house for a few hours. Brody wife Erica (unknown age) was drunk and on heavy pain drugs from a recent surgery. She just kept saying "I cant believe he did that. To us. To you kids." Ecetera. Well I would have never guessed her next move. She pulls out her phone and starts talking about how he had reached out to them with very vulnerable and blunt words. It was along the lines "I want to play with a water gun in the woods behind my house". She keeps talking so I keep reading. She had told him to " get out of here with that" and "shut the fuck up". This was a month prior to it happening.

I reset them because they didn't say anything to anyone. No call or message about it to any of his kids.

Erica reached out to me a year later to give me my dad's computer (they didn't know the password and couldnt wipe it to sell it due to skill issue) and lost it on me. Saying things like "if didn't do nothing to you, why are you treating me like this"

Well flash forward to now, ive moved states and shes messaging me trying to be friendly.

AITAH if i choose to continue to be distant instead of letting it go?
