Is it flaking if she cancel a daye three days before a date? Does it justify a no contact?

Months ago I had invited this woman out to theater one month before (because of tickets), but three days before the performance she wrote:"can we make it another time? I need to go to..."

I considered a way of flaking, so I didn't propose a reschedule (and neither did she), but I reduced my interest for her, I stopped texting, almost a no contact... she was initially nice to me, now she's neutral.

I never discussed the matter with her. I dont really know wheter she simply wanted to avoid meeting me or wheter she really wanted to reschedule.

After months, I wonder wheter I was right in no contacting her.

Is it flaking if she cancel a daye three days before a date? Does it justify a no contact?
