Just married for a week, my friend told me that my wife used to sell in a hotel. My friend also ordered it, and I have been doing it for about five years, but my wife didn't tell me.

As you said, this aspect belongs to your wife's personal privacy, and she doesn't want to tell you, or because she is afraid of losing you or for other reasons, but as a husband, since she is married, the two sides must have an emotional foundation, otherwise they will not walk together. I suggest you find a suitable time to be honest with your wife and ask what happened and whether it is necessary for both sides to continue communication. Because marriage is a major event in life, not only for two people, but also for two families. We must treat it with caution. If you really have feelings, I suggest you let bygones be bygones and live your own life.
