BOY PROBLEM!!! Does he like me??? HELP?

I have known him since my junior yr in high school he was a senior then. Now he is a freshman in college. I am a senior.He was in my class junior yr. But now he is in college. I send him a friend request on facebook. I liked his 2 pics on facebook and he liked my whole picture album? I asked him why did u accepted me to your list. I am your friend right??? He said yeah. I asked him why don't u add more girls he just said that he does not need that many girls? Whenever he posts something on his wall I click like it. When I'm on facebook I like his pics and the places he went to. He does have girl friends on facebook about 3 american . But he rarely knows them. There is one girl who likes his status everyday. She must be stalkerish. I rarely like his wall posting maybe 3x time a month. I like his status.I can't understand does he LIKE me??? He's Pakistani Muslim. I'm Sikh Indian. I think he likes me more than a friend. Cuz he chats with me like 1 or 2 hrs. I am the only Indian girl who is from his school and were in the same class too but we never talked.....we basically were not friends then..... we become friends on facebook.
