How did her husband express his regret for cheating?

The correct choice highlights the emotional aspect of expressing regret in a direct and heartfelt manner. When someone apologizes for their actions, especially in the context of infidelity, it demonstrates an acknowledgment of wrongdoing and a sincere desire to take responsibility for their behavior.

In this scenario, the act of apologizing implies not just an admission of guilt but also an expression of remorse and a wish to mend the relationship. It suggests a willingness to recognize the pain caused by the infidelity and to seek forgiveness from the partner, fostering an opportunity for dialogue and potentially reconciliation.

The other options, while they relate to the concept of cheating, focus on different nuances. Admitting to cheating conveys a recognition of the act itself, but it lacks the emotional weight of an apology. Forgiving her for cheating implies a different dynamic where he is in a position of offering forgiveness rather than expressing regret for his own actions. Confessing to cheating also denotes the act of revealing the truth but does not carry the emotional connotation of remorse that an apology does. Thus, apologizing for cheating stands out as the most comprehensive way to convey regret in this context.
