Jen,

I can understand why you are still hung up on this man.  Man oh man, 6 years and only meeting face-to-face 3-4 times?!! I cannot see how anyone can sustain a romantic relationship like that.

It sounds like you are still wanting to be in relationship with him and he is ambivalent because of the logistics.

I think he is ambivalent because of the close emotional bond he has formed with you but is frustrated because of the lack of a physical/sexual bond.  He cannot let go of the emotional closeness but knows that a true romantic relationship is not feasible because of the distance.
