Search Results: i''m separated

Well this who i know from before college, stares and lock eyes with me when he sees me for 5 months now. He becomes really quiet or doesn't talk at all when im around, even when he's with his friend. We talked a bit before college but he didn't know anything about me. He knows that im going to college which is with same building as his cause he saw me with his good friend from my college. He sometimes acts really silly and sometimes he's obvious.

He hangs with one group in which is one girl. They separate from that group sometimes, or hangs out all together. She meet his good friend from my college and has one from his high school on her fb. Some of those group think that there's maybe sth between them cause they always hang out in past 3 months. It passed her birthday and valentines day and they are still single both.
Also he never changed the way he acts around me even in front of her! He stares, become quiet and stiff. Once he was passing with her and she went to elevator. He saw me with his good friend (i'd beg infront of me and he was like lurking and walking to side and us). We all smiled and he wanted to come but he was late for class so that friend told him to go. 2 days later he was passing with that girl through my college even he needed to walk 4 floors to his colleges.

Also i never saw them hugging of stuff.. well he did it once but when i wasn't around (when i passed him and left but i could saw him).. when i was there he was cold to them and just stared at me.

so long story short me and my boyfriend went out on our first date, and for some reason , one of our friends (she's a girl) happened to tag along. Anyways he bought me some hot chocolate and I spilled it. really it was just me being clumsy and it was super embarrassing. but he seemed to be ok after a bit and kept offering to buy me another one. finally, i let him buy me another one. anyways back to my friend. she was being super annoying and loud the whole time and i could tell he was getting super annoyed. But on top of that she started talking about how i thought this other guy was hot, right in front of him, which i dont but she still said it. after that he looked pissed and we kinda went our separate ways.. i tried texting him and all he has responded with is "its ok, im fine and dont worry about it" and he also responded with " K "... and now he won't respond at all.. WTF SHOULD I DO?
