How to reply when a wife sends a text message to her husband?

If I were you, I would pretend not to know first. Then, the enemy is in the dark, so it is convenient to observe and take more precautions. This short message doesn't explain the decisive problem at all. You want to say something to her, but it's unreasonable. You can't say it's really nothing. It's embarrassing. If there is anything, follow up and collect strong evidence. In this way, whether it is a showdown with her husband or looking for that woman, it is twice the result with half the effort. Take it easy. Impulse is the devil. And it's easy to screw things up. In fact, many times, a showdown is not a good choice. The result of general showdown is that it can be blatant. They used to know to avoid you and restrain themselves.
