She's already admit interest and wanting to go on dates.
She's missed one of our dates but gave me a specific alternate date/time but is being hot/cold about the alternate date.
Her friends are aware of me, going so far to add me on social media/talk to me.
When I don't chase, she comes to me, but when I do chase, she pulls back a bit.
Basically, push-pull tactics. So ladies and gents, what's the best way to actually catch the girl playing hard to get?
