Why didn't my husband dare to let me know when chatting with his brother on WeChat?

That is, he does not love you. After a long time, men will cheat. He can't find happiness with you. You can't meet his requirements. Plus you're old, he'll go out and find another woman. He certainly won't dare to show you the WeChat chat record. It must be something ambiguous and disgusting. You don't need to live with him. Divorce him. He has no feelings for you, and you won't be happy. In the future, you will find someone who really loves you, so that you will be happy.
