I am late to the conversation, but I am glad you came to the conclusion to just let it go. It doesn't matter what she thinks of you. As Advina said, it's clear who has the questionable mind set right now. The fact that she couldn't regulate her emotions in public says a lot, and I am mind reading of course, but I think your hearing what happened kind of pulled at your emotions a bit; thus you wanting to reach out.
But again, I am glad you decided to leave it.
