Does a divorce take place if the wife says the word "You dog" to one of her children, knowing that her husband had warned her against using a specific nickname for his family, "such and such house," and she is now living with an obsession about that, and he fears that his statement, "If you say it, I will divorce you," includes any similar word, even though her husband had clarified that he meant the specific nickname and permitted her to use other words?

The husband's statement "If you say it, I will divorce you" is not an explicit suspension of divorce; rather, it is a promise of divorce that does not entail any immediate consequence. If the husband intended to suspend the divorce, then it occurs if the wife utters the specific words he intended, because an oath depends on the intention of the one who swears it. Since the husband stated that your uttering of words close to the nickname does not fall within his oath, there is no problem. Nothing has occurred on your part that necessitates a divorce. You should be wary of divorce-related obsessive thoughts and rid yourself of them by seeking Allah's help and making abundant supplications.
