Michael and Katherine have enjoyed a long relationship together even before they tie the knot. But Michael does not hide the fact he's a womanizer and sex addict, cheating on Katherine during their pre-married relationship. Because Katherine is genuinely in love with him, she is willing to overlook this and believes that perhaps marriage will change things.
