A 2011 study conducted by Indiana University, the Kinsey Institute and the University of Guelph, for instance, found that 23 percent of men and 19 percent of women had reported cheating. (To put that in perspective, research from the 1990s found that 10-15 percent of women reported being unfaithful, according to ABC News.)
What's to account for the uptick in cheating wives? To get some answers, we went straight to the source, asking our female followers on Facebook and Twitter to tell us why they think women cheat. (Curious to know why men cheat? Click here to see what our male followers had to say last month.)
