"The book says most affairs aren't about finding a new partner," Mark whispered, finally meeting her eyes. "They're about a lack of communication in the old one. I didn't know how to tell you I felt invisible, so I chose the coward’s way to feel seen."

Mark looked down at his hands. "That’s what everyone says. Men cheat because they’re bored or because someone younger looked their way."

They realized that the affair wasn't the end of their book, but a violent, unwanted editing of a chapter. By exploding the myths—that it was only about lust, that it was Elena's fault, or that they were doomed to fail—they began to build something new. It wasn't the marriage they had before; that one was gone. This one was built on the rubble, grittier and far more honest.

The hum of the espresso machine was the only thing filling the silence between Elena and Mark. On the mahogany table sat a worn copy of Peggy Vaughan’s Infidelity: Exploding the Myths . Elena had bought it a week after the "discovery," and it had become their shared, painful bible.

"And I thought if I was the perfect wife, it could never happen here," Elena replied. "Myth Number Three: 'Affair-proofing.' I thought our 'good marriage' was a shield. It wasn't."
