Not your typical love story question?

I crashed course with this fascinating 21 year old girl who captured my heart. We had this synchronicity of mind that let us know what the other was thinking from a distance. She told me how amazing i was and said on several occasions that if we had met when she was 22/23 she would have proposed to me and married me in an instant. Then suddenly i am without her and being ignored. It was the shortest sweetest thing i've ever experienced and i don't understand why it had to end the way that it is. Is being a good, honest, passionate lover a recipe for disaster? must i become cold and callus to attract the one who brings my world closer to the heavens above? she included me in her journal and let me know about it, the physical aspect was there, the mental/spiritual was there, the socializing aspect is what really did me in i'm afraid. chance brought us together several times without our own doing. she understands what's been lost and i just dont understand what would propel her to destroy something mutually beautiful. she will never find another who loved her the way i did and she knows it, is this why she left? Have any of you girls done anything like this to a guy?
