My four-year-old daughter told me that “Mommy’s friend” slept on my pillow whenever I traveled. That very night, I canceled my flight and returned to look at my own home as a stranger would. My wife had kissed me at the door, pretending to be sleepy. My suitcase was headed for the airport, but my heart was already on its way back. And my little girl, without knowing it, had just broken the secret she had been forced to keep.

She went quiet. I had started therapy a few weeks before. Not because I wanted to save the marriage. Because I didn’t want the hatred to become the way I would raise Sophie.
