What Buddha's techniques I can use to uproot deep craving for a woman's love?

I am not geographically close to this woman, nor do I ever talk to her, she's just my teenage obsession that lingers on my mind. I am too much attached to my perceptions about how she is, and because I cannot be near to her geography nor can I talk to her because of a past issue, I feel emptiness inside me. I feel lonely and I crave presence. I satisfying this craving my visualisations and fantasies. How can I get rid of this from deep inside. I have gotten rid of this from conscious thinking, but deep inside it still exists. Currently I am practicing 32 Body part meditation, Vipassana and Anapana Meditation. Can you suggest any specific exercise that would help me with this particular issue?
