The three week point itself isn’t necessarily significant. It’s just something she’s realized while looking back, that she never realized while it was happening - essentially showing her own lack of “staying power.” It’s actually the point in most of my own relationships where either A) things end or B) something happens that changes the relationship which ultimately contributes to the end, which is why I chose it (and I liked the way it sounded over nearby options). It’s kind of the point where the rose-colored glasses come off I suppose.

I don’t like giving away too much plot-wise, because I always may change it, but I guess you could say the ending is “happy,” but not fairy tale-esque. No prince charming to run off and marry to pursue their happily ever after.

One of the men from the story does resurface though. The “happy” angle isn’t so much about the guy, but about her realization that she doesn’t need to “settle” just to not be single over 30 - basically that yeah, this guy she’s crazy about is back in her life, she’s thrilled, and it may very well be that he’s her “Mr. Right.” Then again, it may very well be that it’s just going to be another great three weeks, and she’s finally OK with that. More internal “happy” than external.
