Search Results: i'm scared to move on

I meet guy 10 months a go and he stared at me, try to initiate a conversation and little show off. We talked a bit. We didn't see esch other for long and now we're ond different collages with same hall. He always stares at me even move to see me if he can or i can't see him. When im close he's shy and quiet and has that blank face always. Sometimes even ignores me. That's have been for 3 months now. He's talkative and hans with girls and laugh with them, hugs them and stuff. When i was in cantine to his table he coulnd't look at me. He was quiet until i moved. Then he become talkative. He turn his body torwards me. When he couldn't see me his firned was lookig me while talk to him. When he was leaving he like scan room with his sight (he couldn't see me). When i was with his good friend and he was passing with his girl friends. They gone to elevator and wait for him. I had my bag on table in front of me. He looked at us and walk to side and like lurking behind my bag. Me and friend started to smile and then he. He started to walk to us but friend told him to go in elevator. He waved at us and smiled. Day after that he was passing by me through my collage to go to his. He never gone that way to his collage.

His good friend have my number.
Guys why does he act like that? Is he just playing with me or likes me a lot but scared to talk to me?

My boyfriend had a huge thing for this other girl sinse before we met but told me she wasn't interested and that i didn't have to worry. From what i coukd tell she was just shy but maybe im wrong. He seems to have this strong bond to her i can't break. (I really hope its not love.) the other day she found out about us and started to cry. She actes like it wad nothing and walked out. He went after her. They were talking for a long time so i decided ti check on them and when i came out i hear him say "im in a relationship right now. But if it doent work i would really like us to try" and he was hugging her close to him. When i asked him what happend later he said he was just talking to her because she was scared and sad and he wanted to 'help' and ' get clarity'. Im starting to wonder if i even had a chance, like maybe i should move on. Should i be worried? Is this bad?
