Is it Islamically permissible to divorce a wife who threatens suicide, and how can one absolve himself of responsibility for the other girl who cannot bear to leave him, taking into account the prohibition of polygamy in Tunisia?

Acquaintance and love relationships between men and women who are not mahram are not condoned by Sharia. If a man's heart becomes attached to a woman, marriage is the solution. If he is unable to marry her, he must turn his heart away from her. Divorce for a need is permissible, and a wife threatening to kill herself is a grave evil. It is advised not to rush into divorce and to review the matter carefully.
