So there's this girl...?

and i don't know what to do. i love her and we're always going on and off with things; you know what i mean? we dated once, broke up, got back together, & broke up again. now we're best friends & i'm perfectly content with that; only she any i are sort of doing the "friends with benefits" deal. which i'm REALLY okay with (haha) but we keep re-conecting you know? & i know she feels it too, but for some reason (& yes, i've conveyed this to her) she just doesn't want to be with me. i know that there are feelings there; i think the reason she's not into dating is because she wants to "expand" i suppose. see other guys you know? which i totally get. should i stay friends/FWB with her & just wait for her to see how much we belong together or should i just stop thinking about us being together completely?
