Search Results: a guy you like goes missing

I am at the end of my patience. I usually dont do things like this, (tell a guy I have feelings for him) but I've been so lonely at college and I don't know, I'm angry at myself rn.

So it all started a few weeks ago. he saw me playing a game on my computer in the lab, and said, "oh you play that too? thats so cool!" and I said yeah and asked for his username on the site. and he typed it in for me. Then, there was a meeting for people who were fans of the game and we were both there and the sparks just flew. He was asking me questions about myself to keep the convrsation going and went out of his way to shake my hand and tell me it was nice to meet me for the second time when it was time for me to go.
After that, things got funny. Once, he came in the lab and we started grinning at each other and he came over to tell me what a great job i was doing with the game i was playing. I grinned and told him I was using the hint button. he playfuly said 'you cheater' and went over to his usual seat. The day after this I was nervous and I decided to sit in the main library instead of in the lab. he saw me.
I was in the lab thouhg after that everyday waiting for him so I could see him. He NEVER came in. and this is SO not like him. he's ALWAYS in the lab. SO FINLLAY, he comes in, with a haircut, and goes to his seat adn sits down to work. wehn he gets up to leave, I look at him to see if he'll look at me to say hi, and he didn't, he just walked out?
Then he invited me to play that same night on teh site. I said 'sorry!' about missing his invite because I wasn't online. he didn't text anything back!
Then I waited some more days for him in the lab, and today I see him when I walk in, and he smiles at me and waves from his seat and I grin at him. I don't know. maybe he was just being friendly. but I'm crazy about him
