Does he like me, or am I just receiving the wrong signals?

There's this one guy I have in one of my classes, and I just can't help but notice certain things from him.

At first, I thought it was just a coincidence. I would catch him looking my way a few times in that one class; or sometimes at lunch.

There were times when I felt he was invading my personal space. Whenever we're lined up to go to the cafeteria, there's always that one spot in the line that we stand in. Though we mind each others' business.

At times, I tend to look around the classroom, and he does, too. Occasionally, our gazes lock, and it's kinda awkward.

He brushes past me at times, and sometimes it's so crowded in the line or hallways, I'm forced to be squished(I don't think "squished" was the right term to use, but hopefully you get what I mean) against him.

Whenever I'm just standing in my group of friends, talking, he randomly wanders near my standpoint and talks with his friends; or butts into my conversation.

It seems he pays attention to me... sometimes(?).

For example(there's more than one example, but I don't have enough room to list it), I remembered how a friend of mine(she likes to tease me) randomly bear-hugged me from behind, making me sway from side-to-side, almost losing my balance. Then, he comes up to us from no where, saying things on how she like to harass people. O.o

I've actually tried talking to him before. We held a private conversation one morning, set up by my best friend, who has known him longer than I have. I only stated how I noticed those weird glances(including how uncomfortable I felt about it) and asked him if he liked me or not. I was actually planning to say more, but I was stuttering a lot and looking away. It's the first time I've ever actually dealt with this sort of thing so... eh. He replied saying he didn't like me and that the glances were just because of his karate instincts. Also, I think this is important: as I approached him and asked to join him, he said he knew it was me. Since my best friend kept giving hints on who the girl that wanted to talk to him was.

I was hoping after we had talked, everything would be resolved and just... stop. Unfortunately, it sort of seems to have gotten worse. Now, it feels like he's teasing me.

Though the thing that's been bugging me the most is the fact he's younger than me. He's one grade lower(or however you name it) than me, but our birthdays are only a few months apart. It's just that, when I think about relationships, I think the guy's supposed to be older than the girl(though I know that's not always true). I'm not the type of person who is straightforward and dare I admit, is shy. I've been wondering though, am I hallucinating? In that one class that I have him, I'm always with my best friend; and I wonder if he likes her instead? And I'm just seeing the wrong things? It's really confusing to come up with a conclusion since I don't have all the facts yet, but that's what I have on my mind... :/
