It probably might mean just that... that he really likes you... though there are times when he means it as a joke or something and it depends on how he says it. There are a lot of meanings about what a guy actually means when he says things like that. Unless he has major confidence running through his vains he isn't going to say that outfront instead he might hang with you for a while and show tiny gestures of care... now I'm no expertie at this, but then go for it... you don't want to regret turning him down after making him go through that confessing his feelings...
It usually means that he really likes you and you really like him.
It means that he really likes you and that your perfect for him.
It probably just means that he really likes you!!!
It means he likes you - a lot.
It really likes you. Trust me. It is true.
If a guy says that you are pretty it does not mean that he likes you. He could like you, or he could just be paying you a compliment.
It means whatever you feel when you think about what it means. Enjoy the compliment but don't read into it.
either was really in the conversation or likes you
You can't really tell what it means. Maybe he likes you. He wants to protect you.
It means he likes you but it depends if he smiles when he says it.
It doesn't necessarily mean that he likes you in that way, but it could mean that you are important to him.
He likes you
