You know that person in a group of friends who's always, always, always dating someone, to the point where something might be a little wrong with them? Yeah, I'm that person. I did the math recently and I've spent a third of my time on this Earth in serious long-term relationships.

As something of a next-level serial monogamist, I've experienced more than my fair share of breakups, mostly scattered across four U.S. cities: New York, N.Y.; Princeton, N.J.; San Antonio, Texas; and now, quite recently, San Francisco.

Why stay, if San Francisco makes life's transitions so much harder? It's a hard question.

We all have complicated relationships with this city — its dysfunction, its challenges, its many wild beauties. There's lots to love here, lots we want to fix and more we do not want to lose. Leaving is always bittersweet.
