It's difficult to determine the exact reason without more context, as people's behaviors and motivations can vary widely. However, I can provide some possible explanations for why someone might tell their friends that they stay alone while actually being in a relationship where they live with their partner:
Privacy concerns: Some individuals prefer to keep their personal life private, especially when it comes to their romantic relationships. They might feel uncomfortable sharing details about their living arrangements with others, even if they are in a committed relationship.
Independence: The person may want to maintain a sense of independence or individuality within their social circle. By presenting themselves as living alone, they could be trying to assert their autonomy and avoid being defined solely by their relationship.
Fear of judgment: In certain social circles, there might be specific expectations or judgments associated with living with a partner. By saying they live alone, they might be avoiding potential criticism or gossip.
Relationship issues: It's possible that there are underlying relationship problems or tensions that the person is trying to conceal from their friends. By not revealing the true living situation, they may be avoiding discussions about the relationship's dynamics.
Conflicting living situations: In some cases, people might not be living together all the time due to practical reasons like work, studies, or other commitments. In such situations, they might emphasize the times when they are living alone to simplify the explanation.
Miscommunication or misunderstanding: There could be miscommunication between the person and their friends. It's possible that the person thinks they are discussing a specific timeframe or situation when they stay alone, while their friends interpret it as a permanent arrangement.
Personality or social reasons: Some individuals tend to share partial truths or withhold information about themselves due to their personality traits or social tendencies. They might not feel comfortable fully opening up to others about their relationship.
To truly understand the reason behind this behavior, it would be best to have an open and honest conversation with the person involved. Communication is key in any relationship, and discussing their motivations directly can help clear up any misunderstandings or concerns.
