Sister-in-law, I hate my sister-in-law

Your experience is similar to yours. However, we are handling it much better now. My boyfriend and I are going to get married the year after next. In fact, you can get married this year. However, because my future sister-in-law is not married, we have to wait for her to get married. She is 30 years old and unmarried. The strangest thing is that she has never been in love. She is lazy at home. My future mother-in-law also said that she can be diligent and do things neatly. I looked in the cupboard. I have to help her wash clothes every day. Forget it. I always say that I don't study hard. I have to take the judicial examination every day, and I have to take care of my family's work, big and small. How can I have time to study? As a result, one day, she said that she didn't work because she wanted to exercise my work and make me angry. I didn't say anything at that time, so I took it out on my boyfriend. However, he is a filial child. I got a beauty card and went to get a beauty treatment every day, so I hid. Later, I bought a rolling pin myself, went to the park and called my boyfriend. He thought I was going to hit him. I picked up a rolling pin and hit it on the ground, scolding his sister. He saw that I was really tired living in this house, so he advised me. In fact, we have quarreled countless times because of his family, and I also hate me. Anyway, you should think so. Your sister can't rot at home all her life, even if she is rotten. If we really quarrel with her mother-in-law's house, it is normal for us to be sad, but the people we love. My friend said to me, why does my sister have so many things? Actually, it's because we robbed her brother and her pride. Let's pay the price. Don't hate it.
