Married men changing their Facebook status to single has become a common phenomenon. This could indicate a variety of reasons, including feelings of being tied down in a relationship, wanting to maintain privacy, or a desire to appear single to attract potential partners. It could also be a sign of distress in the marriage, such as a lack of trust or a need to feel in control. Ultimately, it is important for couples to talk openly about their relationship status and understand why their partner may be expressing a desire to appear single on social media.
