Girls, I really don't get it. Help me to understand?

This whole idea of pushing someone away or "testing" guys just to see how much they are willing to come back? I mean would you date a guy who kept pushing you away just to see if you would come crawling back? Don't mistake me, If she legitimately doesn't feel appreciated and I really want her then I will try my damnedest to get her back. But if it's just the first date and a girl is trying to put me through the ringer instead of just enjoying the date then immediately I think insecure,immature, and waay too paranoid for my tastes. but maybe there is something I'm missing. if you liked a guy, why would you purposely try to push him away?
