Did I miss a clear green light after a past toxic workplace dynamic, or was I right to stay defensive (22M / 20F)?

The Context:

A while back, I (22M, 5'6") had a volatile, back-and-forth dynamic with a coworker (20F, 6'0"). It was a mix of emotional games, negging, indirect social media posts, and late-night venting. It eventually hit a wall when I reached out to her while out of town, and she responded with a "we don't work as friends" boundary.

The Reconnect:

Once we no longer worked together, the daily workplace friction vanished. Months later, completely out of nowhere, she reached out to me. We ended up on a 45+ minute FaceTime call that went surprisingly well, and she even texted me again the very next day.

Where I Hesitated:

I was so conditioned by our past drama, my own height insecurities, and a defensive fear of getting shut down again that I stayed passive. I never asked her when she was free, and I never suggested getting food to catch up in person. Eventually, the momentum died, and the window closed.

My Questions for Reddit:

Was a 45+ minute FaceTime call plus a next-day text a clear opening to ask her out, or was it just casual boredom on her end?

Did my defensive mindset completely blind me to a normal, low-stakes move (like grabbing food)?

How do you break out of a defensive mental loop when a past messy dynamic suddenly turns positive?

Be brutal. Tell me where I overthought things or dropped the ball.
