I just got an e-mail from a girl I briefly dated nine years ago and haven't seen or heard from since then. She's apparently divorced and now engaged again. I'm married with a kid on the way. Clearly, there's nothing romantic any more, but it still feels weird. Variations on this theme seem to happen about once a year to me, and I've never really had a good handle on what to do or how I'm supposed to feel about it. Anyone else experienced this sort of thing?
