If you want to marry more than one wife, then you must be intelligent. Do you know why your wives will play pranks, manipulate, lie, etc, especially if they are not religious. Your first wife has complained to you, please listen to her, she is making sense. When you told her, you would be bringing the second wife to join you in the three bedroom flat. She rejected the idea, but after much pressure, she agreed. She has been calling your attention to the excesses of the second wife, that during her days, when both of you are in the other room, she will intentionally scream and moan loud, disturbing the whole house. She is doing, 'pepper them', for the first wife. As the husband, if she cannot stop, then get another apartment for her. Brothers should know that plural marriage requires financial resources, separate apartments, even within the same compound is on point, the era of keeping two wives in one room should be discouraged, nothing is wrong if they have three bedroom flat each, may Allah separate us from poverty. It is not about jealousy. The first wife is absolutely right, religiously, and morally, and it is not proper to expose your sexual pleasure to other people. Always pay attention to details. Abu Sheikh
