He might be lying for several possible reasons, including seeking approval, hiding vulnerability, avoiding conflict, defending his self-worth, succumbing to peer pressure, trying to protect someone else's feelings, self-deception, or creating emotional distance. Often, lying can be a way to maintain a certain image or avoid uncomfortable truths, either about himself or in the relationship. Some men lie because they feel societal pressure to appear strong and may fear admitting weakness or failure. Others may lie to avoid confrontation or to shield others from hurt, or because they struggle with accountability and emotional openness.
