Input: I hooked up with a family friend a 2 months ago, she's my aunt's friend 10 years older than me. We hooked up and she asked me not to tell anyone, so far I haven't told anyone. 

She has a falling out with my aunt and our friendship is a bit estranged, don't really know what to say about it. 

A bit backstory, I've told my uncle that I've had a crush on this woman for a while, then sometime after Halloween my uncle and I have a falling out (he's a bad drunk, I tried to take him home, he didn't like my approach) 

Find out yesterday that he hooked up with that same family friend and she asked him not to say anything, especially to my family (I was asked the same thing). He immediately told my aunt and she told me. 

I tell the family friend that he's told people in our family about it and she should be aware, am I an asshole for this?

TLDR; 
Hooked up with family friend, uncle hooked up with family friend, he told everybody, I told her that's everyone knows about them AITA

telling a hookup about someone else sharing their business
