Fear a cheating spouse? Author gives tips to check

By Patricia Reaney

NEW YORK (Reuters Life!) - Worried about why your partner is always working late? Suspicious about repeated hang-ups on the answer machine? Dismayed by a dwindling interest in sex?

It could be just job pressures, wrong numbers and a low libido, or your spouse could be cheating, according to author Robert C. DeMoulin who has written a new book, "Exposing Infidelity," to help worried partners tell the difference.

DeMoulin told Reuters that the book not only reveals what signs to look but also includes evidence-finder software to provide proof:

Q: What made you write this book?

A: "About a year ago I was sitting in a restaurant with a friend and I overheard three or four guys talking about how they were cheating on their wives and got away with it. One of them said, 'Hey, someone should write a book about how to cheat.' I thought that was kind of interesting but really bad karma. But what about the reverse -- writing a book about how to catch someone who is cheating. I started researching it and here it is."

Q: How easy was it to write?

A: "It was more difficult than it might seem. I created an advertisement and recruited people who claimed to have had an affair for more than a year. Interviewing them and learning how they had done it, how they kept it a secret and some of the techniques they had used forms the core content of the book. It was fascinating to research."

Q: So how do you spot a cheating spouse?
