The relationship between mother-in-law and daughter-in-law is not good, and there is a sister next to her, which is even more difficult! If you want to maintain this marriage, you must have certain methods. First of all, we must stabilize our husband. You can find an opportunity to ask him out to talk and tell him that there is no emotional crisis or contradiction between you. You are a good couple. You love each other and have a good life. Let your husband agree with you at this point. Then, when you treat your mother-in-law, you must be docile, filial and kind to her. Make her think you're not bad. Between mother-in-law and elder sister-in-law, we must hug each other. We don't want to sow discord between them, but we can't always face two people! It will be good for you to make one of them have a slightly better impression on you. Although it is difficult, you must hold your mother-in-law, at least let her feel that her daughter-in-law is ok. Let her husband talk to her mother-in-law when he is free, and tell her that he loves you and will not divorce you. Besides, divorce is not good for him and his family. Find another one. I'm afraid it can't be anyone! It implies that it is difficult to have a good wife with such a mother-in-law and sister. Let mom have some concerns. In this way, my sister will feel isolated. If possible, let the husband communicate with the elder sister again, let the elder sister put an end to it, handle her own affairs well, and don't let her sister-in-law worry. In short, the contradiction between you and your mother-in-law and elder sister-in-law must be supported by your husband, and you must have him to help you with many things. You can't let the whole family work for you. You can't do it alone. At the same time, we should win over our mother-in-law and isolate our elder sister. This is your basic strategy. Bless you!
