What is what does it mean when a guy says he cares about you?

When a guy says he cares about you, it generally means that he has feelings for you that go beyond just being friends. He may be expressing his affection for you and saying that he values your happiness, well-being, and overall worth as a person. It can also mean that he is willing to support you through any difficult times and wants to be there for you whenever you need someone to talk to. It's important to note that everyone may have their own unique way of expressing care, so it's important to communicate with the person in order to fully understand their intentions and feelings.
