You take the L here and learn from it.

Don’t idealise people, and don’t let your feelings run away with. What you feel isn’t what she feels.

To you, this was a once-a-lifetime-opportunity and perfect connection. To her it could have been a guy she seems to be clicking really well with but she’s just got out of a relationship with a really neurotic guy so she’s a bit wary.

You let your projection of feelings for her cause you to overplay your hand because you were largely thinking of what the interactions meant to you instead of balancing that with what they may mean to her. Take people as they come, not as you feel they might be. She told you she’s bad at texting and you still went for her over her lack of texting after that and ultimately sabotaged yourself because you got in your head too much (like being aware of her activity on socials whilst tracking her text progress with you, that signals you were really giving a lot of attention and thought to what she was doing).

Loosen up a bit, learn, and use the lessons to handle the next time like a champ.
