What is the ruling if a man said to his wife, "If you don't want me, then you are divorced," and she replied, "I do want you"?

If a man says to his wife, "If you do not want me, then you are divorced," and she replies, "I want you," then no divorce occurs. In such formulations, it is a condition that the wife articulates with her tongue her desire (i.e., acceptance), such as by saying, "I have willed it."
