If you started as a friend, acted as a friend and did all you could be a friend, then chances are that yes, the girl's gonna consider you as a friend rather then a potential lover until possibly much, much MUCH (i'm talking several years down the line when you honestly don't even think about hooking up with her) later it might happen spontaneously.
Until then, can't blame the girl for treating you exactly the way you've acted,
Hoping for lovesies under such situations, besides showing that this friend thing was but an elaborate charade, is impractical and nonsensical.
Those "dicks" have done naught but gone out and seeked a relationship and been forward in their intentions. That is less dickish then pretending to be friends with a girl for the dim prospect of having a chance later on, working on it for months, then make a move when the girl has lost all interest.
