The short version is: My daughter fell in love several years ago with another teenager; both were dubs in good standing, both later reproved for expressing that love in some manner not platonic. Boy moves away. Girl moves away, in another direction. Three thousand miles separate them. Calendar rolls on, seven years pass. They start to talk on the phone. He is DF'd, not remotely interested in going back, she has stopped going to meetings and associating with dubs, wants nothing to do with it.
They arrange to meet, have whirlwind weekend, in order "to see if there's anything there." For her, there is. For him, there isn,'t apparently. He doesn't call for a week, then when confronted says he has a lot of things to think about. A few weeks later he calls and says he has started going to meetings again and "feels pretty good about it."
So they're done.
What advice should I give devastated daughter?
