Lovely poem, but the last question killed it!!
It would have made much more sense if the last question was stated like so:
Why? Because throughout the entire poem, the narrator (or speaker) is talking TO this girl - or wanting to talk to this girl. So it would only make sense if that last question was phrased just as the previous ones, with "you".Will you ever be mine?
Great poem, Sprout. Keep it up.
