My wife and her boss have gone on a trip. I didn't know until I came back. My wife said nothing. Who should I trust? I don't think my wife is that kind of person

Don't bother yourself. If your wife's feelings for you have not changed, but she insists that nothing happened, you should trust her. Because even if she has something, it's temporary. Her white lies don't mean to hurt you. She still loves you very much. Besides, if you don't think your wife is that kind of person, you should trust her. Unless you don't want to let go, think things over, which will hurt each other.
