Why Men Cheat

Brian and Anne say they never thought they would have to deal with an affair in their marriage. Anne says Brian was never gone in the evenings, they were emotionally connected, and they had sex every night. Yet Brian was secretly having an affair on his lunch hour at work.

"I was always under the belief that affairs happened to people in either bad marriages or where there's no sex going on. And because we had both of those things, I was really unaware of how easily I could slip into an affair," Brian says.

Brian says he started having his affair with a person who at first was just a friend. "And then you develop some sort of a connection with them through some sort of common interest," he says. "I didn't choose to go have an affair. It just sort of happened."

Gary says Brian is right that most men meet the person they have an affair with in one of two places—at work or through a hobby. "It begins as an emotional relationship. There's a friendship that develops. It's not just looking for the sex," Gary says. "We all have this picture of cheaters as the bad guys. They're horrible, rotten, not nice. No, they can be nice people who get lost, who do the wrong thing—and they can be your husband."

Anne now runs a support group for betrayed spouses called Beyond Affairs Network, and they both conduct Passionate Life seminars across North America for individuals and couples looking to improve their marriages.
