Author Ruth Houston, who made the study of infidelity her life's work after she discovered her now ex-husband cheating 11 years ago, says having a spouse and a lover is a dangerous juggling match on such days as Valentine's Day.

A woman, meanwhile, is more likely to say she must visit a sick or distressed friend, Houston told the Fort Worth Star-Telegram. "If a person -- particularly a man -- is cheating, he is going to buy gifts. There's no way around it if he wants to stay in a woman's good graces and in her bed," she said. Houston is the founder of the Web site InfidelityAdvice.com, and author of "Is He Cheating on You? -- 829 Telltale Signs."
