The way I see things, if a girl doesn't want to be exclusive or comes up with the "I don't know what I want" its (In my experience) for a few things...
She doesn't see you as a relationship guy. Why? You may not meet her "standards" for relationship, keep in mind, girls will fuck a bad boy, but they will not keep him. She may not see you as a sure couple, all the chasing thing and "playing hard", being a challenge is good if you want to keep it casual, but if you want the title of being boyfriend and girlfriend, she needs to have the security that you will remain with her. When a girl goes into a relationship, she wants a stable guy, a sure guy, this doesn't mean you have to be 100% there for her.
I don't know how your relationship is with this girl, but that could be a point, you probably haven't shown her that you're something else than a fuck buddy. This has happened to me in the past, this girl was totally infatuated with me, and when I told her to be my girlfriend, she said she wanted to be sure of me, I was playing the whole being a challenge thing. She said that I wouldn't call her for days, and she would wonder if I was still interested. This of course makes her want you more, but to be honest, who wants a boyfriend that won't call? Or someone who won't even drop a text to say hello? ... No girl wants that, for a relationship. A girl wants a boyfriend who will actually care about her, without being a wuss, which is what PUA should help you with. Not being a needy wuss, which is what 90% of guys out there are. Ghandi once said that cowards are unable to express love, love is the prerogative of the strong.
Relationship and gaming are two different things in my opinion. Its ok to play a challenge at the beginning, but if you want something serious, you need to start showing those small details that separate the fuck buddy from the boyfriend. Be a gentleman, show her that you care for her, that you will stay, be the best you can be, so she WANTS you to be only hers. But don't become a needy wuss!!!
Now... there's always the chance that she doesn't want a boyfriend because she wants to sleep around with many guys, she's young and in college, she has the right to experiment.
Ask her
