Hmm is she hinting here on just playing games?

She's either interested in dating you or just wants to sleep with you. Think about her past relationships and try to see if a lot of them were purely ual (if you even know her that well, you may not which is a sign in itself). If so, she might just be interested in and not an actual relationship. If you don't mind the games you guys are playing then just go along with it, but if you want the relationship to go anywhere you should tell her so that she understands. It all depends on what YOU want from HER.
