There's this guy I like who I've met before, but we've never really talked to, just been introduced and briefly talked once. Last night, we were both at this party and dancing, and his friend suddenly introduced himself to me, and introduced the guy I like to me again (he repeated the intro twice). So we danced together for a bit and I saw his friend kinda smirking in the corner.
Later, he was standing by himself and I was standing near him and I said to him "Hey" and he said "Hey" but I got nervous and didn't know what to say, so I said "Um actually, don't worry." He looked confused and said "Ok". For the rest of the night, we glanced at each other a bit. At school we saw each other, but neither of us even said hi and he didn't even look at me or acknowledge me. I got his ICQ, but he doesn't say hi.
Is he interested or not? I'm really confused! Maybe he knows I'm interested (from my signals or from his friend)? He's not really shy, but not really outgoing either. Guys, please help!
