As a general rule of thumb think about all your past girlfriends and all the girls that were head over heels for you. How long did they make you wait before they returned your call or wanted to hang out with you (prob not very long). Compare that to how this girl is acting and you will have ur answer.
Chances are that if you have to ask this question, then she is not that interested in you. If you pursue you run the risk of her looking at you as desperate and it being counterproductive. And if she is interested in you and is still playing these childish games then that is indicative of a chick that has issues.
Its been repeated over and over by myself and other posters. 95% of the time if a girl likes you and you guys have mutual chemistry with each other, the girl will make it easy for you to hang out with her. In fact shes going to be excited to hang out with you. She might play little coy games in the beginning, but that is anti slut defense fake resistance.
There are tons of chicks out there who will like you for you (assuming you are a non desperate, socially well adjusted guy). You just have to find these girls. It might take you ten girls in order to find one that you click with, but she is out there. Why waste your time with a girl that is acting like this?
