Most logical thing for you right now would be to pick up yer phone and call her. You might want to consider waiting for a few days (two is enough, not three as some may say) and go along the lines of "we had fun at the alley, and today I was reading this movie review(or whatever kind of fun thing to do you came up with), so I figured you might want to tag along". Pick a thing to do and stick to it! Have a plan, a course of events etc.
You can probably manage things from there on. And yes, do read the DJBible.
Cheers.
