Does a divorce take place if a man says to his wife, "You are the air I breathe," then holds his breath intending divorce after a month?

If the husband says to his wife: "She is the air he breathes," and then intentionally holds his breath, intending divorce, nothing is binding upon him. This is because divorce does not occur by action, even if intended. Rather, it occurs by an explicit utterance or one that is ambiguous accompanied by intention.
