I saw my brother WeChat having an affair with others. Should I tell my sister in law?

Tell her and let her handle it herself. Besides, my brother is fine. My brother is three years younger than me. He is over 30 years old. Now he has a family, a wife and children. I won't talk about my childhood experience. Let's talk about a few small things in adulthood.

The first small thing is that on May 20th this year, I saw my brother's red envelope on WeChat. My evaluation: this person is finally beginning to understand the customs. You know, he is not romantic at all, and he is absolutely economical for men. Then I found a message on QQ, and my dear brother sent me a red envelope! The first time! He finally began to warm up.

Secondly, my husband grew up by the sea and loves seafood very much. My brother is good to my husband and my husband is good to my brother. My brother brought tea to my husband on a business trip, and my husband asked for my brother's number when he sent clothes. Actually, it's all for my own good My brother said to me seriously several times: Sister, when my parents are old, go to my house to support the elderly. Just come and see them then, don't take them away. He has prepared two houses.

Then, my parents' house will be demolished, and my brother's household registration is all there. My brother has reached an agreement with his parents to share some of the demolition money with me. For example, once I went home, my sister-in-law cried. It turned out that she saw a strange girl on my brother's mobile phone asking for dinner together. My brother explained that the car behind me collided with his car when I went to work the other morning. Seeing that his car was all right, he let the owner behind him go. As a result, the girl insisted on leaving the other party's number and said that she could contact him if there was anything.

A week later, I happened to see the news that the girl asked my brother for dinner. My silly brother told me: What's there to cry about? I'm not going. Later, I taught him a lesson, but he still thought women were too busy. Between my brother and sister-in-law, I never express any opinions, and I will let my brother be better to my sister-in-law in private.
