Where did I go wrong? And, Should I still persist?

I made this mistake long ago, it was uncalled for you to send the “if you’re too nervous, Id understand” text. All she did was not respond to your text which is nothing to take personally or be reactive at all about. You could have rather followed up with “Yo sexy” or “Taking your time I see”

You should have built more investment
"Where are you from originally" "What's the story with this pic?" "How's the tinder life treating you " something to get her talking more

doesnt look like you did anything wrong tbh, she probably just got nervous. this has happened many times to me I would move on, i doubt she would even respond if you tried to re-engage anyways
