Does a divorce occur with the husband's statement: "You will not travel except as one divorced," if he intended it as a threat and not as a divorce?

What your husband uttered is not explicit regarding the occurrence or suspension of divorce; it might be a promise of it. If he intended to threaten you with divorce should you travel, then this is a promise by which divorce does not occur unless he actually divorces you when you travel. However, if he meant that if you travel, then you are divorced, then divorce occurs upon your travel, even if he intended it as a threat.
