12 Surprising Facts About Infidelity

Fact #2: Men usually cheat with women they know.

Cheaters don't generally pick up random women in bars. "My first husband cheated on me with a childhood friend," says Diane* from New York City. "His family was close to her family, so they never lost touch." Intimacy expert Mary Jo Rapini explains, "A lot of women think that all cheating women are floozies—not true. The relationships are usually friendships first." A good idea: Make sure your husband feels more connected to you than to his business partner. "Spouses go to work, take care of their kids and do separate things at night. That has to stop," says Rapini. She suggests always going to bed at the same time and cuddling.

Fact #3: Men cheat to save their marriages

"Men love their spouses, but they don't know how to fix their relationship problems, so they go outside their marriages to fill any holes," says licensed marriage and family therapist Susan Mandel, PhD. Men want it all and have the skewed notion that another woman will make the longing for something more disappear. Then, they can live happily ever after with their wife—and their mistress—without confronting the real issues.
