A man who says he loves you doesn't like to mention his wife in front of you. Why?

He did it for your own good. If you talk too much, go back to kneeling keyboard in case someone hears you one day.

Moreover, if caught, his wife may not be so heavy when fighting, otherwise he will feel uncomfortable if you are injured. So the less you know about his wife, the better. When one day he annoys you and leaves you, you will understand why you can't say too much. Stay out of danger and find another one.
