When I read the original story, I had to double check the username to make sure it wasn't one of my friends posting about me. The beginning of the story is so similar to my situation. The week before I left for school this year I met this awesome guy who I hung out with everyday that week. And then we talked everyday on the phone for about a month and a half. If the story ended here with the great conversations and fun of that week I would be tempted to say, "Oh, why not move to be near him" BUT there are other factors.
Has he gone to visit her? That's very important, whether he's busy or not. Has she gone to see him? And if so, was it the same? (Its really hard to suddenly be with someone in person again after having a "phone relationship." Expectations are confused.)
They need face time before she makes a big move, otherwise she may end up HORRIBLY disappointed.
