What is the ruling on a wife posting pictures of young men she does not know out of admiration for them, without her husband's knowledge? Is she considered a betrayer, and what should the husband do if he finds out about this?

A man must be keen to marry a righteous woman who protects her husband in his presence and absence. A wife posting pictures of young men under the pretext of admiring them is considered an act of betrayal to the husband and a prohibited act that violates Allah’s command to lower one's gaze, even if it is not infidelity in the sense of committing indecency. If the husband learns of this act, he should address the matter with admonition and advice, reminding her of the prohibition of the act and that it provokes the husband's jealousy. The wife must repent to Allah for this sin.
