Is there any consequence to a husband telling his wife, "I don't understand why you let your hair down," whether he stops short during the sentence or completes it?

The statement made by the husband does not constitute a divorce. If the husband explicitly says, "I divorce you from my bond," or "I separate from you with my body," or "I release you from my hand," no divorce occurs, because what is connected to the speech diverts it from its intended meaning. Therefore, the man is not bound by what he said, and he must beware of obsessive thoughts (waswasa).
