Does divorce occur with the husband's statement: "You are divorced if you did it?" after the wife answers "yes," even if he has forgotten the details of what happened?

Whoever is afflicted with sins should repent sincerely and conceal them. You erred by confessing your past sins to your husband. Repentance, seeking forgiveness, and Allah's concealment are sufficient for you. As for divorce, it has not occurred, because your husband only asked, and you answered, and the marital bond remains intact.
