Why Men Cheat

Men have a winning mentality, Gary says. Just think about how the men in your life act while watching their favorite sports teams. "They love to win," Gary says. "Does he have ownership in the team? It looks like that. But as long as they're in the game, even to the very end, they'll watch. Once it's a blowout and they know their team can't win, television goes off. And what a lot of men will say to me through this research is, 'I just felt like I couldn't win.' Now they might not have been great guys to live with, I'm not saying it's her fault, again. But if you want to secure your relationship and understand and have the knowledge of men, make them feel like they're winning with the things that they do for you."

Don't be afraid to praise your partner or tell him that you appreciate what he does, Gary says. "We get married because we want one person in the world to really think we're wonderful for doing all the things that we do. We all want the same thing," he says. "And the more we give it, the more we get it in return."
