My sister works as an administrative director at a fertility clinic in Miami. She called me at 8:03 in the morning and asked, “Where is your husband?” I replied, “In Denver, at an investment conference.” My sister lowered her voice and said, “No, he’s here, at my clinic, with a pregnant woman, and he just tried to use your health insurance.” With her help, I mapped out a plan for revenge. The next morning, Daniel called me, completely losing his mind.

I smiled, entirely without humor. “How nice. It even has a view.”

Daniel leaned toward her. “Marissa, don’t listen to this.” “You told me you were already separated.” “I was.” “You slept at my house last week,” I said. “You used my mug. You asked if I wanted to order Thai food. You weren’t separated. You were comfortable.”
