Search Results: loosen up

I know one guy for a year almost. We meet and he seems confident, he talked really much and like he's enjoying the attention he gets.
We looked at each other, lock eyes, he tried to initate conversation and stuff like that back than.
I've never told him anything about me.
After 6 months college started and he seems to always at least notice me but usually he prolong looks at my direction and stares, and few times we locked eyes. He becomes quiet around me when im close to him even with his friends. He has mostly female friends and he's loosen up with tham but never infront of me.
He sometimes acts "cool" and like that and sometimes really weird.
So that's been going for 6 months now and he still does all of that.
He found out 2 months ago that i know his good friend and he has my number (his friend) but this guy never made a bold move.

Guys, does happenes to you that you maybe like some girl for months and never approach her?

So there's guy on college (he's acquaintance of mine, but we've never talked really). So for last 5 months i always seems to find him looking, staring in my direction and in me (after some my testing if he looks in me and he does and after 58302 times looking at me ahaha). Well he's doing it and when im close he becomes quiet or talk little and when im far he's talkative.

He doesn't know anything about me till 2 months ago, when he saw me with his good friend from my college. He was loosen up then and he smiled for first time infront of me (and acted funny- i'd beg infront of me nad he was walking to side and us and like he lurks). 2 days later he was walking through mycollege. So after that we didn't saw each other for 2 months and now he stares again.

He's seems confident guy around anyone except me. He changes his behaviour even when he's with his friends. I've never heard him talking much infront of me and i meet him first time he was pretty talkative.

So 6 months ago i meet one guy in group. He seemed really confident and talkative. He was sitting next to me and he talked non-stop. I got up with cigarette in hand and he turned to me and looked and aske me where am going; like it wasn't obvious. After 3 months i saw him again in that group, but we weren't same shift. So i was inside and outside. He came and i saw him looking through window, we locked eyes then. He was walking inside-out couching, asking for cookies and other stuff like he wants attention. So when i got out he turned to me and locked eyes wit me. I passed him and he turned and said 'bye' to me and friend.
After that i saw him on college next time 3 months later. He didn't knew anything about me except we want same college (he got in i didn't, but we go in colleges in same building).

So we see each other 1-2-3 times a week. He always seems to notice me, looks and stares at me every time he sees me for past 6 months. No one acts like that. Sometimes my friends wouldn't notice me and he would.
He becomes really quiet when im around even with his friends. He's pretty stuff and quiet and serious when im around and has blank face.
He was loosen up only when he saw me first time when his good friend, he was smiling. I'd beg infront of me, he noticed us and started to walk to us and side and like he lurks. We all smiled and he was so cute. Friend told him to go cause friends were waiting for him in elevator. He waved, smiled and said bye with weird voice. 2 days later he was walking through my college to his by stairs. He never done that. His good friends is okay with me and he's always nice and has my number. He could took it from him but he didn't.

It's so much to write but this is short. What's up with this guy? What sould i do.
