<human>: I met this girl [18f] 2 weeks ago at a friendly get together (i'm a 19yo m), and after what seemed like a dull night we ended up hanging out for an entire week afterwards.

We did things like cliff diving, wakeboarding, partying, and even watched a sunrise. Bear in mind that not any one of these activities were done while we were alone.

We started snapping and texting for a few days; she would ask me if i was into her jokingly and i would play along, and i surprised her with lunch one day (it went perfectly). Throughout our days spent together we would often go off on our own for anywhere from 15 minutes to 3 or 4 hours and just talk and flirt, but no moves were made past shoulder massages and hand holding.

A few days ago she went to the beach with her family and best friend, and i stopped talking to her as much so she could enjoy her vacation and kept to mainly snapchats. I was in a comfortable place, or so i thought, as my friends would tell me about how she always talked about me and complained about how we had to part ways for college so soon. 

After about a day and a half she stopped responding to snapchats, so naturally i laid off a bit. I then randomly get a saddening message from a friend that showed a screenshot of a message he got from my crush saying "Could you please tell rme94 in a sweet and kind, very sweet and kind way that i don't have feelings for him but he is very sweet and kind."

When i told my friends most of them were fairly surprised, but obviously i obliged and backed off even further. Whenever we snapchat now she sends me pictures of her with other guys, tweets about them etc; however, she still acknowledges me with favorites/likes and what have you.

Tomorrow i'm going to a concert with some friends and i'm 95% sure i'll end up seeing her there. I'm pretty sure she has an idea that i'm going but i haven't told her straight up that i'd be there.

Can you give me the gist of the text in a nutshell?
<bot>: Girl was super flirty and openly interested, goes on vacation with family and friend and suddenly loses all interest. Possible confrontation tomorrow.
