DOES HE LIKES ME?? help!!!!!!?

I am Sikh Indian girl. He is Pakistani muslim boy. 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 the only girl who's indian her friend rest are boys, He was in my class junior yr. He always looked at me? But we were not friends than. But now he is in college. I send him a friend request on facebook. He accepted me? He chats with me like 1 hour or longer. but now he has not chatted with me for 2 weeks. 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 dont you add girls to your friends list? He said he dont like that many girls? I asked him why u add me to your list. I am your friend right??? He said yea. He chat with me like a 1 or 2 hours???
