Oh good now that you know she only sees you as a male girlfriend, you can take the necessary steps to go no contact and to learn the lesson that you shouldn't be a girl you find attractive friend but simply ask her out on a date and if she tells you "no" then you shouldn't have anything else to do with her.
Hoooray... now that you know you were just her girlfriend with dangly bits, you can wash that girl right outta your hair FOR GOOD.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
