My friend thinks i'm being thick headed for moving on, would like to hear asktrp's opinion. Long story short: Asked a girl (via text) if she wanted to join me to go shooting. She suggests "maybe" having her friends come along then asks if another day would work. I say no (busy that day anyways) and made plans with some of my friends to go shooting. Then I get a message "Is there anything you would want to do tomorrow that's not shooting?" Since I already made plans, I say we'll do something another week. A few days later, I get a message "Reminded me of you" with a pic referencing a book we talked about.

With that out of the way, does "is there anything else you wanna do..." mean she just didn't want to go shooting? and does the subsequent text suggest she's still interested?

As soon as I read she was thinking about inviting friends, I lost interest. Dunno if I put too much thought into that.
