My brother's married wife gave me two thousand red envelopes, and my sister-in-law said something, and my wife cried! What should we do?

I have been an orphan since I was a child. I don't know why my parents abandoned me. Later, my adoptive parents adopted me and gave me a happy home. They also have a son, three years younger than me, who is my brother. Although he is the biological child of my adoptive parents, they always treat us equally. Even in many things, I think my adoptive parents treat me better because they always think I have no biological parents.

Although my brother and I are not related by blood, we have special interests since childhood. Because adoptive parents have been educating us to love each other, my brother and I have a very good relationship since childhood. In fact, the foster parents' family conditions have not been very good, but they belong to the kind of people who are particularly selfless and great. They always want to leave the best things to my brother and me. Although the family conditions are not very good, we insist on providing for the two of us to go to college.

My brother and I are also quite disappointing. We are both admitted to a good university. My wife and I met in college. My wife is very beautiful and I love her very much. She likes me too. My adoptive parents also agree with our relationship. At that time, my brother and I had a hard time going to college, but when we got married, our adoptive parents gave us 50 thousand yuan.

After my wife and I got married, life was not bad. I have always felt that I should thank my adoptive parents for making me have such a happy life today. Now that my brother has graduated from college, he is getting married. When he got married, I told my wife that I wanted to give my brother more red envelopes, but my wife refused. I always thought I should repay my adoptive parents, so I finally secretly gave my brother and sister-in-law 30 thousand yuan.

On my brother's wedding day, my wife wrapped a red envelope of 2000 yuan according to her own ideas. Who would have thought that at the wedding, when my sister-in-law received a red envelope, she even said to her wife: Sister-in-law, what should we say to thank her? Brother has given 30 thousand, and you gave 2 thousand here. Hearing this, my wife quarreled with me at the wedding and cried and joked at the wedding, which suddenly turned into a joke. I saw the disappointment in the eyes of my adoptive parents, and my brother quickly returned the money to me. Everyone said, what should I do now?
