A: Well I had a friend like that. Just talk to him as friends and set the difference between just friends and likin someone. Even though its cliche you should actual say how you feel and tell him that you two can just be friends.Also tell him that he's cool or something nice about him.
A: Sometimes it takes a while for people to be close when they just start going out. You can ask I'm how he really feel about you when you see him in person. If he didn't like you he probably wouldn't have asked you out(except some foolish guys do). Give him a little while to come around.
