Cheating on a partner is not something many people readily admit to, so it’s near-impossible to put any exact figures on the issue.
One study might definitively say it happens in 70 percent of all marriages, while an independent expert could suggest it happens in anywhere from 20 to 60 percent of relationships. However, while (again) the percentages vary wildly, there is one common theme running through all of these statistics: men tend to cheat more than women.
