The Physics of Leaving

She left on a Tuesday, which felt like a cosmic joke — Tuesdays were for swimming at the YMCA, where I'd watch her cut through the water with that relentless, elegant efficiency that had first made me love her. We'd met three years ago at the city pool; she was teaching a private lesson, her voice carrying over the splashing chaos, and I was pretending to read a book while actually studying the precise angle of her dive.

Tonight, I'm sitting at a baseball game alone. The ticket was meant for us. We'd planned this for months — seats just past first base, where her brother played semipro. The crack of the bat connects to something hollow in my chest. That sound used to mean summer evenings on her balcony, cheap beer and cheaper ambitions, the way she'd explain baseball statistics like they were love languages.

"You're overthinking again," she'd say, and she'd be right. I think about the night she told me she was leaving for San Francisco. We'd been arguing about nothing — dishes, really, but it was never about dishes. It was about how I'd stopped swimming. How I'd stopped showing up to her games. How I'd stopped being the person who met her at the door, breathless and grateful.

Now I'm running, truly running, down Montgomery Street at 2 AM because leaving the stadium early felt like giving up. My lungs burn. Good. Something should. The pavement is unforgivable, hard and cold, and for a moment I understand why people move to cities like San Francisco — places where you can disappear into the fog and start over, where no one remembers who you were when you loved someone who eventually decided you weren't enough.

A text lights up my phone: "Did you make it?" Her brother. He must have seen my empty seat.

I type back: "Got stuck at work." Another lie. The truth is I'm stuck between who I was and who I'm becoming, caught in that terrible middle ground where memory and possibility collide.

The swimming pool is closed for renovations. The baseball season ends next week. I'm still running, past shuttered storefronts and the occasional taxi, running like I can somehow outrun the physics of loss — how things separate, how momentum carries you forward even when you're screaming to stop, how some people are just meant to drift away like silt settling at the bottom of a pool you haven't visited in years.

Tomorrow I'll go back to the YMCA. Tomorrow I'll get in the water. Tomorrow I'll start learning how to move forward instead of just running away. Tonight though, tonight I let myself run through the empty streets of a city that feels too large for one person, alone with the echo of a baseball game I never watched, carrying the weight of a swimming lesson I'll never take.
