My husband said he was heading to Denver for a work trip, so I went to my prenatal appointment by myself. While I was waiting outside maternity triage, I suddenly spotted him hurrying down the hallway with his arm wrapped around a very pregnant woman, carrying her overnight bag like this was something he had done countless times. Then she grabbed his sleeve, looked directly at me, and said one word that changed everything.

The chronicle of my own marital coup d’état did not begin with a shouting match or a shattered glass. It began with a text message at 8:47 on a crisp Tuesday morning.

My husband said he was flying to Denver for work, so I went to my twenty-eight-week prenatal appointment alone. The air in our home that morning had tasted of expensive dark roast coffee and practiced routine. Adrian had kissed my forehead before sunrise, his lips warm against my skin. I remembered the distinct, rhythmic click-clack of his leather suitcase wheels rolling across the hardwood of our foyer. He had turned back at the door, his eyes crinkling in that apologetic way I had loved for five years, and apologized three times for missing this appointment.
