M. Gary Neuman shares the findings of his extensive research with unfaithful husbands that turn the conventional wisdom about extramarital affairs on its head: It's not all about sex; he's not just a pig; she's not prettier than you; and he really does feel terrible about what he's done.

So why do men do it? Neuman reveals the emotional roots of male infidelity, explains how men experience and express their emotions differently from women, and lays out a simple series of actions you can take to ensure that your husband never strays. These steps help you build a deeper and more intimate relationship and a stronger, happier marriage that is more supportive and rewarding for both of you.
