The wife accidentally saw her husband's text message not returning.

You lack communication. He is busy with his work. As a wife, you should care about him with love. There are many temptations in society, such as money, beauty, status and so on, which can change men. This is not a question of who is right or wrong.

He does have another woman. If I were you, I would keep him. Practice (1) He will take care of him when he goes home, cooking, washing clothes and taking care of home. (2) Look at your parents-in-law more during this time, maybe you won't have a chance in the future. (3) If two months have passed, tell him calmly that you want a divorce. If he agrees without thinking, you can go at ease.
