She is not available and seems unsure of what she even wants. AND you have feelings for her. I don't see how reaching out would be beneficial to you. It would only perpetuate the upset and/or expectations (if you want more than friendship).

Let her go. Live your life and open your heart up to other possibilities.

Who knows, she may come back to you if she gets herself sorted out. OR you may meet someone available and who fully reciprocates your feelings. In the meantime, move on.
