I can think of several possibilities here. He may have been just reliving his youth. Maybe you are "the one that got away". I think many of us wonder about a former girlfriend who may have been "the one" and how would our lives been different if we had made smarter decisions when we were young. Another possibility is that he just likes to reonnect with old friends. I have been talking to old friends that I have found on face book, etc., and it never occurred to me that they may read more into my contacting them than I meant.
