Is the husband considered unjust to his wife when he divorces her, acknowledging her shortcomings towards his mother through complaining and causing harm, despite his affirmation of her good companionship and her fulfilling her duties towards him and their children? Is the wife sinful if she refrains from visiting the husband's mother or speaking with her and blocks her from her phone, in the event the husband reviews her? Is it better to try to win over the husband during the waiting period (iddah) or to wait until each of them regains their composure?

If your husband divorced you because of your abusive words towards his mother, then this divorce should not have occurred. You should not have abused his mother, for showing kindness to the in-laws strengthens the marital relationship. You are permitted to stop visiting your husband's mother, but it will negatively affect your relationship. As for completely cutting off communication with her, it is not permissible in Islamic law, because the Sharia (definition) forbids boycotting a Muslim for more than three days. We advise you to reconcile with your husband and come to an understanding with him so that he may take you back, and to show kindness to his mother, for that is part of a wife's good character.
