Children...Money problems...Boring sex life... 

These are just three of the reasons why women would expect their men to stray. In reality, a relationship doesn't have to be on the rocks for a man to step out on his insignificant other. Or vice versa. While lack of sex might seem to be the frontrunner in excuses for infidelity, it actually isn't the most common cause. Do you have a cheating spouse? Check out the following signs he's stepping out. 

Why He Cheats 

Marriage counselor M. Gary Neuman, author of The Truth About Cheating, surveyed 200 men to find the real reasons why men cheat. He found that as few as 8 percent of them listed sexual dissatisfaction as the main reason for cheating on their wives. They may feel guilty, but that does not stop them from participating in the infidelity. "Men are good at compartmentalizing feelings," Neuman explains. "They can hold on to their emotions and deal with them later."
