Why is he acting this way?

I'm not sure if I like him in that way but he seems to be giving off odd signals.

Ok I guess you want to know more.

Uh I already have his number, and yes when I text he almost instantly texts back; and he asked me for mine it wasn't as if I stalked him.

When he talks to me he seems to not look directly in to my eyes which is really strange.

He fixed my collar today which left me speechless thinking where did that come from.

He compliments me kind of constantly actually. Whenever I complain about my hair being curly he instantly says he likes it curly. Which I suppose every guy would say when a girl complains.

He acts extremely different around me when he's with his guy friends; almost if he's shy or playing it cool.

That's about it really.
