Every chick is a bit of both of those two categories. Any chick will do everything she can to get your attention if she likes you (and for some chicks only if she knows you're into her too because she's shy) or alternatively when she has your attention she will try and hold on to it for as long as possible. You just have to limit the amount of attention you actually give to her to keep her interested - if you worship her and leave no time for yourself you become boring to her and she will move on. That said when you give her attention you should be the guy complimenting her and making her feel better then all the other girls. All chicks love that stuff if you do it right, and it will keep her thinking about you and have her seeking your divine attention even further.
It's really not that complicated, kinda like a balancing act, with the reward for good balance being lewinskys
