You have no obligation to have sex with the person you marry. Sex is not an obligation. Sex is meant to be a fun, pleasurable activity.
That said, the husband is the asshole here. He had Sex with someone else without informing his wife. Did he use protection? Did his new partner have a recent STI check? He potentially exposed his wife to STIs along with lying about his whereabouts. He manipulated his coworker, who obviously has a lot of self worth issues, into believing that he thought she was special. He's trash.
