Most Helpful Girl
She was probably interested. And wanted to test the waters with you without you crawling all over her.
And you had no follow through. You should have just made something up on the fly when she asked what you had in mind.
Cuz you not having had a date plan probably made her assume your first plan was a Netflix and chill.
And on top you waited a week to get back to her. Making her think you aren't interested.
I'm not even terribly attractive and I get asked out every other day. So you waiting a week meant other guys probably showed interest and follow through while you were twiddling your thumbs
