DOES HE LIKE ME??? I DON'T KNOW? 10POINTS?

you are speculating that he always looked at you. Him not replying for a long period of time during the chat is showing that he doesn't show much interest. If he is then he would put more effort into the chat sessions. You are also speculating that you are the only girl he befriended. You will know if he likes you when he actually put effort into asking questions about you...instead of making you wait.
