The Great Gatsby, wayward men

Could you please tell me if "wayward" in this extract from the chapter Three of The Great Gatsby means "unfaithful":

One of the men was talking with curious intensity to a young actress, and his wife after attempting to laugh at the situation in a dignified and indifferent way broke down entirely and resorted to flank attacks—at intervals she appeared suddenly at his side like an angry diamond and hissed “You promised!” into his ear.

The reluctance to go home was not confined to wayward men

Thank you.
