How can a woman deal with her current situation, which combines her marriage to a married man, the cessation of financial support she used to receive, and her mother's repeated demands for money, all of which have negatively affected her psychological state and led her to contemplate suicide?

The wife has the right to dispose of her maintenance money, which she received from her husband, as she wishes, such as giving it to her mother or donating it as charity. She is not obliged to inform her husband of this, unless the husband gave the money for the purpose of spending from it reasonably and preserving the remainder for him. In this case, she does not have the right to dispose of it except with his permission.
