She probably is flirting, but panicked when I suggested meeting her at her place. She is so Avoidant to close relationships that even if she did want to date, I doubt if I'd be into it. I first met her five years ago and she's been "You stay on your side of the planet" since then. I have a need for a shorter feedback loop.
I first saw my ex-wife at an astronomy club meeting and I resolved to talk to her after the meeting, but she got up and left at the halfway point. I met her again on a field trip that the astronomy club took to Yerkes Observatory, and after that, she asked me if I could come to her apartment to help align her sister's telescope. I said, "Sure."
Total time, less than one month. And my ex was both sx-last and pretty Avoidant, too. I really don't need a woman who is 60X to 100X more avoidant than my ex.
I mostly posted that vignette so that people could see an ESI, albeit an Avoidant one, in action.
