To be honest, I feel this is more about finding a place for those who got away. Between those girls you were too shy to talk to, those that left for other lands, those you couldn't keep up with or couldn't work out how to get by - all our lives are filled with the those we were sure to be the one, and that isn't what it turned out to be. But with all those that are in his past, he remembers why he felt the way he did about them seeing it through the "heart fire" -- so he thanks them (for more who they were, as much as who they are) by sending them his love.
