The separation of the two brothers is very troublesome. How to divide it reasonably can make parents worry.

The Bible says that "it is better to love each other by eating green vegetables than by eating fat cows". Imagine if there were no such disputes in your family. In fact, the real contradiction is not caused by your family of four (parents/brothers/you), but a "war" between your sister-in-law and your wife. Therefore, in order to really make this family harmonious, one spouse must make sacrifices to satisfy the other, but according to the current situation. One is threatening divorce, and the other is using why you have to suffer losses as an excuse ... This is a painful experience for your parents. They raised us and worried that we would not be able to marry a daughter-in-law. They have given enough, why are they still angry with you? From the tone of your question, I can see that you are the key to the safety of this family. Persuade your daughter-in-law and be considerate of your parents. You will be wronged more and even make this family happy. Everyone in the world is willing to build their own happiness on the suffering of others, but this is not a way for "people". If you really want to solve this problem perfectly, people's real happiness is not to have a spacious and bright house to live in. If the family is not harmonious, even with these conditions, you are on pins and needles every day. On the contrary, although you live in a narrow place, your body is very wronged, but your heart is very spacious, and your parents are very pleased to have such an understanding son, so true happiness belongs to your heart and personality instead of space. I think you know how to do it. God bless you!
