Search Results: the stranger is it real

So 6 months before college i meet talkative and confident guy. He seemed like i catched his eye but i didn't think that back than. He didn't know anything about me except we want same college ( i didn't got in, he did).

So after 6 minths we saw each other on college, different colleges same building. So every time we would see each other he would look, stare and lock eyes with me. Sometimes he would move to place he could see me. When he saw me with his good friend, from my college, 2 days later i meet him on my part of college, where he never gone before. Sometimes he would do that someone who is not interested wouldn't do.
I was watching other people - friends, stranger and how they act when they see me and it's not like his noti even close.
I wrote whole story few times on GAG and mostly people say that he likes me but doesn't know what to do cause we never really had real convo :/

Second problem is his friend, who he hangs for past 4 months. They hang in group and their friends told me that they sometimes separete from group. His girl friends meet good friend from my college. And that girl have on fb one his from high school. Some people say that there's sth between them cause thay hang a lot (guy-girl friendship; don't know if it's just cause of that because i've never seen anything more than that between them).
Confuses me cause he acts how he acts when im around even infront of her. If im close he wouldn't talk much, we locked eyes infront of me, he look prolonged in me, becomes like stiff, never huged or anything else girls infront of me (he does that when he taught that i'm not around anymore),...

So guys, my friend asked good friend does he have girlfriend (he didn't wanted to say until she give my name) - but i found out that he's single before that from his friends.

How to make him more effective and to show what he really wants?
