According to a new study (that’s how most bad news starts) women are most likely to cheat on their husbands between 6 and 10 years into a marriage. The study suggests that in the early and late stages of marriage women are more likely to stay faithful. Between 6 and 10 years they are likely to stray due to the pressures of facing middle age with the same partner. Men are likely to stray if they have been married 11 years or more.
