As I mentioned elsewhere
, my wife and the other guy have acknowledged their feelings for each other, but he's very hesitant to take the next step. This is understandable but frustrating.
She dated him for a while in high school, but never (even to this day) progressed to a physical relationship. She had a kind of "background" missing him all along but never really acknowledged it thinking that it wasn't meant to be... then when she found him a few years ago she found out that her family members intercepted letters between them and caused each to think the other had broken contact without warning or explanation!
Needless to say, this cast the end of their relationship in a whole new light.
