How to play it with an introverted guy?

Anonymous
So there's this guy, I've kinda known him through other friends for a while but we've never really spoken before. He's kinda quiet, and normally I go for the loud, outgoing, center-of-attention type.

Last weekend, we were out in a group situation, and we got talking. Spent the entire night talking, flirting, making eyes at one another - you know, typical flirting. It was fun!

Thing is, he's really quiet. Up until Friday night, I would never have thought to speak to him. He's not a "shy guy", he's just more of a chilled out, observant, thoughtful and not so in-your-face kinda person who won't necessarily talk to you unless you initiate it. Once you've broken the ice though he'll engage really well.

So my question is, how do I play this? I'm not sure about the quieter introverted types! I'm a loud and outgoing girl, and I always sort of found myself being drawn to other loud, outgoing types.

I know he thinks I'm really cool, he told me so. I don't know if he'd make a move, but I also don't wanna scare him off or come on too strong. Advice from you introverted types?
