I cut this friend off, did I do the right thing?

We’re both female fyi. We’ve been friends since high school and we had so many memories and laughter throughout the years. To be honest she was never that close or great of a friend but she wasn’t bad either.

The type of friendship that if I disappear for a month she wouldn’t ask what happened to me but she be like “hey let’s grab a coffee” when she feels like it, no matter what happened to me, but It was an okay friendship overall

Anyway long story short, there was a guy who she used to have a crush on many years ago, and of all people he had a crush on me! I told her about it like a funny story, I didn’t even think she was still into him since she had other crushes and situationships.

The moment I told her I could feel something changing, she tried to gaslight me into thinking he wasn’t into me and he’s just talking to me as a friend , which was obviously wrong and he admitted that he liked me.

Her behaviour shifted after that, she started making fun of some of my physical features as a “joke” lol besides the fact that she visibly gets annoyed when I get hit on in the street and she didn’t and other signs of jealousy

I ghosted her for about 3 years now but sometimes feel like maybe it wasn’t a big deal and I shouldn’t have done that? Can you guys relate or give me a helpful perspective? Thank you!!
