that means like you like him but he isn't really in to you but he's flattered that you like him.
It means he is interested in you but doesn't want give it away just yet.
There's a possibility that he was really flattered and saw your comment as a hint that maybe you like him too
he likes u
It means no.
Whatever you said to him to make him feel flattered does not need a reply or, you could say 'You are welcome.'
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.
You can tell him that you are flattered but you don't think of him that way.
It means he is the problem....not you
Dude he wants to do IT!!!!!
He likes you
nothing
