Does he like me???? Sooooo confused?

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. I will be going to his college in 3 months. I am Sikh Indian girl. He is Pakistani Muslim boy. He was in my class junior yr. He sometimes looked at me when he knew I was near or close to him? But we were not friends than. But now he is in college. I send him a friend request on facebook. He accepted me. I liked his 2 pics on facebook and he liked my whole picture album? 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. I asked him why did u accepted me to your list. I am your friend right??? He said yeah. he chats with me 1 or 2hrs..I asked him why don't u add more girls he just said that he does not need that many girls?
