And for the record Ryan, if a chick was flirting with me, grinding on me while dancing, I would NOT ask her out on a date.
I probably wouldnt ask her out at all if we hung out with the same social circle and I knew I would see her out consistently. I would simply flirt back a little, dance a little (and dance with other chicks too) and slow play it.
Make yourself and you intentions mysterious with a woman like this. Make her think "Does he like me or just like me as a friend" and you will drive a woman like this nuts to the point that she cant take it anymore and will isolate you and find out if you want to fvck her or not.
You are a chaser. You have to make the chicks the chasers in this game if you want to win each battle and ultimately win the war in this dating game.
If I cant get a chick pursuing me, I dont really push it with her because she is probably lower interest. I normally can get her to start pursuing if I stay cool and quite and for sure stay mysterious and other than some physical escalation, never let my emotional thoughts be know (a mystery).
You have quite a bit of work to do.
