Search Results: guy acting stand off

I meet guy 8 months ago and we talked a bit. He stared a lot and try to initiate conversation, showing off a bit and stuff. We didn't see each other for long time and now we are in different social cyrcles and we are NOT talking a all. He stares and look at me a lot fron afar and when he's close sometimes he looks quickly or ignores me. He would look at me before he would leave room or if i couldnmt see him he would move from group and looked at me. When i was in cantine i was standing next to his table and he was ignoring me and was really quiet and when i moved in line he turn torwards me and become talkative. When he could't see me becoause of some guys his friend was looking at me and tlaking to him. I smiled when i notice he stares at me (last time i saw him before break) and he looked for me in second and look away like behind him. On time i was with mutual friend and he was passing and one of them call him and he just stood there and stared at us. Also after break i was close to table where he was with friends and he was completely ignoring me. That was yesterday and today his good friend who's with me on collage.. send me messege on fb about some class and we talked and he asked me for number so he can send me some photos about that class.. and i gave him and he sand me to fb and we continue to talk on fb and then he sand me on whats up one photo and thats it. So im little bit confused with this situation.. guys what do you mean.. is it my crush wanted number? Why he acted like that when i smiled and he ignore when im close?
I know he's friend have no attention of sth with me and we could talked on fb but he asked for my number? could it be because my crush ask him to do that. And my crush don't habe profile on fb so... My crush is really talkative around everyone but me..

Guys, is this guy just playing with me or he's shy? Most of on GAG told me that he likes me.. but for me it's just very confusing?

We meet 10 months ago. He was sitting next to me and he was reaching for my rubber everytime and then he would change his mind and took friends rubber. When i took ciggarete and get up he turnd to me and looked at me and ask me where i'm going like it wasn't obvious. When i came back he was talking some stories and showing off. Next time i was morning shift and he would come inside and coughing, asking where are cookies,... When i get out he was staring in my face and he said hi and i pass him and he turned to see me and my friend leaving. We hello to him and others. Tomorrow he was ignoring me. we didn't see each other long and we did but now we in different social cyrcles so we don't talk. He stares and looks at me for 3 months now. He would be shy when i was close but somehow he would always turn torwards me his body when he could for example in cantine. When i'm close he become quiet and he would just look at his friend when i would move he become talkative like always. One time when he was like that when i move he turn tarwards me and when he couldn't see me his friend was looking at me and talk to him. Sometimes when he couldn't see me he would move to place where he can. When i was with our friends one of them call his name and he stopped and just stood there and looking at us. Last time before break i saw him staring and i was talking to my friend and i smiled and look at him while i was smiling and he looked for sec and turn to other side. After break i saw him with friends and i was with mine close to him and he was acting like he don't even see me. He would talk to friend and go to other and look what he's doing but i didn't see that he looked at me. So i acted like that also. He sometimes do that and in this 3 months few times.
Why does he do that?
He acts like he likes me most of time and then happen ignoring me. Why? I would talk to him and everthing but he do that and i loose confidence and think that he don't like me 😕
Is he just playing with me or he's shy?
