Weird Girl Situation (at the club)?

[Mike]

I'm studying abroad with some friends in London for the fall. Been here 3 days and have had a blast, though my wallet's been hit hard. Anyways, we went out tonight with a couple of girls from our residence area to a club in Leiceister. After dancing for a while, I caught my friend directing me over to him, whispering "this girl is totally into you!" I look over and see a gorgeous blonde woman which is strange for a couple of reasons. You dont see many white girls going after asian girls regardless of how goodlooking they are, and the way it happened was weird in how they specifically pointed me out to my friends. Anyways, we bought a couple of rounds of drinks for each other and talked (along with her friend). She was very touchyfeely and into my background culture. After a while, she and her friend got up to "go to the loo", so I pass my wallet off to a friend. I'm paranoid about weird things happening that come out of movies like Hostel. A while passes before she comes back but we leave the club together around 3 a.m. I wait for my friends outside, basically ignoring her (to see what would happen) and when it looked like i lost her, she and friend were talking to a couple of guys on the street. The guy she was talking to was all over her and it looked like she didnt mind at all. I finally went over and asked her friend what was going on, and got "this is really awkward". Her friend grabbed her and she rushed over, leaving the other dude screaming for her number. We walked for a little while, before we got to an area for cabs, and she invited me over but some weird feeling told me not to so I told her and ended up getting a number. Is there a next move I should make if I want to see what happens or was this just sketchy from the beginning and I'm an idiot for playing along?!
