How long have you known this young woman? Was there mutual feelings at one time or are you just crushing on her? I don't know the whole backstory but if it was me, and it has been, believe me, I would just tell her how I feel about her. Put it out there. Tell her you want to be with her. Tell her to drop the zero and get with the hero. If she says no thanks then you get your closure. You can then move on, hopefully.
