Ok, so I met this girl at a wedding and we totally hit it off. We spent the whole reception together, then went out afterward and stayed out quite late. She was heavy with the physical contact (not that I'm complaining), but I didn't know if it had turned into an impromptu date or if it was just wedding syndrome.

She gave me her number, so that is a good sign, but I don't know what any of that meant, if anything. I am shy and don't handle rejection well, so I don't want to stick my neck out only to have it chopped off, but at the same time I actually really like this girl. We have a hell of a lot in common and she's just freaking cool. What should I do?
