What is what does it mean when a guy hearts your message?

When a guy hearts your message, it typically means that he likes or approves of what you said. It can also be a way of acknowledging that he has seen your message and wants to show you that he is paying attention to your conversation. However, it should be noted that the context of the message and the relationship between you and the guy will play a role in determining the exact meaning of the heart. In some cases, it could simply be a friendly gesture, while in others, it could indicate romantic interest or attraction.
