<human>: This happened last night, but it was in the early AM hours so technically today.

Anyway, I'm currently doing some travelling. I decided to spend the month of April in London and it's been great, but my time is nearly up. (Source: Calendar)

I decided to do a pub crawl in the Camden area last night. I'd gotten there a bit late so the introduction phase had passed. Being the introvert I am, I wasn't talking to too many people on my own. 

There was a cute girl I'd noticed since I first walked in and I continued to steal glances of her all night. Finally, on the way to the last destination, I struck up conversation with her friend and learned that they all study at Loyola University. I'm a fan of their lacroase team, so I knew that could be my chance to talk to the girl who'd had me so captivated all night. When we all got inside, I made my attempt. Thank you, liquid courage.

We chatted for a bit. She played lacrosse herself! She was funny, knew my hometown (this is big because no one in London seems to be familiar with it), and overall lovely. At one point she said I should get her number so that we might have the chance to run into each other again. This was my drunken, thoughtless response:
"Yeah, but I'm only here for one more weekend so..."

That was it. I killed any notion of ever seeing her again in one sentence. The worst part is I hadn't meant that I didn't want to see her again, because I really did. That was just the logic my inebriated brain decided to put forth...

Kept chatting though and she continued being wonderful. I thought things were going well. I went to the bathroom and when I came back, she and all her friends were gone. Nowhere to be found in the entire club.

Can you provide a brief overview of the text?
<bot>: Coolest girl I've met in awhile literally offered me her number and my response made her think I didn't want to see her again.
