What is when a guy tells you personal things about himself?

When a guy tells you personal things about himself, it could mean that he trusts you and feels comfortable opening up to you. Sharing personal information can be a sign of intimacy and can help to strengthen the connection between two people. However, it is important to respect his boundaries and not use his personal information against him or share it with others without his permission. It is also important to communicate effectively and establish clear boundaries in order to maintain a healthy relationship.
