Hi guys, need a little advice here....

I'm a salsa dancer and there's some HB which i use to dance, and when we dance there's some nice chemistry. But I don't really know how to escalate yet...

Recently i started a conversation with her on facebook, giving compliment to the dance school where she goes, and at the end i told her to save a dance for me the next party.

The next party was this Saturday, first time I saw her, said hello gave her two kisses and told her that we haven't danced yet.... later, we've danced twice (and had some nice chemistry again). At the end of the dance, nothing.... once again.
The next day I sent her just this:

Me: "I'm sorry, looks like we've danced two songs instead of once. "

HB: "Actually it was 1 and 1/2. "

Me:"In that case, we have to compensate that 1/2 dance. I don't like leaving things unfinished."

And she didn't said anything else.

Have i said anything wrong?
Should I avoid facebook messaging flirting with a girl I hardly speak face to face?

Next time you're at a party or whatever and you're dancing with her, and you feel things heating up, go for the kiss! Fuck it, either she will like it, or she'll stop you. Chances are she'll like it, but stop waiting for her to do it, man up! You've got an advantage on a lot of guys, you can dance! Chicks dig that shit. Use it!

Thanks for the advice.

But even though I'm still an AFC, I don't if that's the right approach. I think I have to do some Midgame to escalate after the dance. But like I've said, I'm no expert.
