Cheating Signs: How To Tell If Your Spouse Is Cheating (VIDEO)

How can you tell if your spouse is cheating?

In a video posted on the "Anderson" show's website Tuesday, licensed private investigator Amy Drescher says unfaithful spouses -- especially men -- tend to give a common response when pressed about suspicious behavior (say, new computer passwords or unexplained late nights outs).

"The more [the woman] starts to press him, there's one thing that I commonly hear that she hears from him... he's going to tell her, 'you're crazy' and every time she confronts him again he's going to remind her, 'you're crazy,'" Drescher explained. "It's important for her to realize she's not crazy -- that there is a significant reason why she's having these doubts."

Other signs that your partner may be cheating, according to a February 2010 Marie Claire article? Less sex and a tendency to be overly protective or antsy when receiving calls or texts.
