If a guy acts different around you, does that mean he is interested?

Since day one this guy has not seemed like himself towards me. He was shy when we first met but he is outgoing and friendly with everyone. We only met up a couple of times after that. When he saw me the next time, he was incredibly nice and giddy. We haven't talked since then but I have caught him looking at me a few times and he tried to walk right next to me after class. Then we met up a while later and he was super serious, and not relaxed. He has become more reserved but I saw him do a double take and he has done some weird stuff around me. Why is it that this normally outgoing and friendly guy have a problem to act like himself around me? I do have a tendency to be a bit shy, so would that affect the way he interacts with me?

Possibly, or he is really is trying to show off to you. I do the same things when I want to get your attention.

Get my attention because i'm shy or for another reason?

[IslandGent]

Because I like you. Or you're really really cool to have fun with. Either those two. 75% chance it's the first one.

Not necessarily. Your presence might make him feel uncomfortable.

That's what I thought the last time we met up, like he hated me or something. But we have barely interacted so I don't know why he would have an issue with me? Or at least why I guy would act like that?
