My husband’s ex texted him to say her 7-year-old son was his. I didn’t cry… I texted her husband. I was drinking coffee in our kitchen in Denver, still in my slippers, when an iMessage hit David’s phone and he went as white as a sheet. The screen read “Ashley,” and with that look on his face, I knew breakfast had just turned into a wake. I asked him who it was, and he swallowed hard as if he had eaten a rock.

He nodded. “I swear to you, I didn’t know.”

“I hope so. Because if I find out you did, there won’t be enough lawyers or prayers in the world to rescue you from me.” He didn’t answer.

We arrived at a nice residential building—the kind with a doorman, well-manicured landscaping, and neighbors who greet you as if they don’t hear shouting through the walls. Mark was waiting outside, a child’s backpack slung over his shoulder.
