I agree with Star* and anthem_shouter. To me, it's most definitely about that "moment" that you've been waiting for for an entire lifetime, whether it be one concerning love, family, etc. (most likely love, in my opinion. Who doesn't love love? XD) You've missed that one moment because you didn't realize it was /the/ moment, and it came so quickly that you didn't realize it had passed. You were still waiting for it, until you realized "hey, that was it...it's over" and well...it leaves you feeling defeated as hell.
