The Mathematics of Leaving

Emma stood at the kitchen counter, staring at the amber bottle of vitamin D pills Richard had left behind. Three months since the divorce, and she was still parsing through his debris like an archaeologist of her own marriage. The pills were expired now. Everything was.

Her iPhone buzzed against the granite — a notification from LinkedIn. Richard's profile picture, that confident smile, appeared beside a congratulations message for his new role at some venture capital firm. The bull market had been good to him. It had been good to them, once, back when they were young enough to believe that compound interest applied to happiness too.

Barnaby, their golden retriever, nudged her hand with that wet nose that demanded attention regardless of human heartbreak. He was Richard's idea — a family dog for the family they'd never have. Emma looked down at him, at the graying muzzle, and felt the old familiar ache. She was forty-two. She'd thought she'd have children by now. Instead, she had a dog with someone else's last name tattooed on his collar tag and a mortgage on a house that felt too large for one person.

"You want dinner, bear?" she whispered, scratching behind his ears. The nickname had started as a joke — something about how he shuffled like a hibernating animal when he woke — but it had stuck. Now it was just another word that tasted like loneliness.

Emma grabbed the vitamin bottle. She marched to the bathroom, to the toilet, and dumped them all. Thirty capsules spiraled into the water, a cloud of amber refusing to dissolve. She flushed.

The phone buzzed again. Another notification. This time, she silenced it without looking.

She walked to the window. Below, the city was doing what cities do — carrying on without her. Somewhere, Richard was probably pouring expensive scotch and telling stories about his brilliant ex-wife, the one who'd understood him when no one else did. Or maybe he wasn't. Maybe he'd already moved on to the next narrative.

Barnaby appeared at her side, leaning his warm weight against her leg. Emma rested her hand on his head, feeling the steady rhythm of his breathing. Tomorrow, she'd take down the photos. Next week, she'd sell the house. But tonight, she stood in the amber glow of streetlights coming through windows that needed cleaning, and for the first time in three years, she let herself imagine what came after.

The vitamins were gone. That was something.

She turned off the kitchen light. In the darkness, she could almost believe she was starting over.
