In his research as a marriage counselor and for The Truth About Cheating, Gary says he found several signs that a husband is cheating.
Gary says another precursor to a man's cheating is when he suddenly cannot stop talking about another woman. "So many women, when they find out their husbands cheat, they know right away who he's been cheating with because he's been talking about her," Gary says. "He's been talking about lunch and the project and they're building things together, whatever. They're doing all kinds of stuff together."
