Does the husband's statement to his wife, "I am not your husband," after her statement, "You are not my husband," during a dispute between them, count as an allusion to divorce?

This wording is an allusion (kinayah) and not an explicit (sarih) pronouncement of divorce. Therefore, divorce does not occur with it unless the husband intended it. This is because an explicit pronouncement results in divorce without the need for intention, whereas an allusion does not result in divorce until it is intended.
