Is he testing the waters or does he not like me?

we met in another play where he was in it and i was his quick changer, then we chatted on and off on myspace. . Then I was in sound of music & how stupid for me not to notice right? apparently he had was lighting crew for my show, what a coincidence but I didn't notice, how funny, he thought it was. well.. he hugs me &we catch up. and my thoughts started wondering about him , and felt kind of nervous when he was close. later girls in my cast are introducing themselves to him, and I am there & i am say u know me, and then he shakes the rest of everyone's hands & then he hugs me. and all the girls say how do u know him and he says, "oh she dressed me." I think i felt heat in my cheeks and everyone was saying, oh u dressed him!. I said yeah, but I dressed everyone, to save from more embarment, but i think it was pretty noticable that i was embarred. there are more iffy actions. also..today, i finally stroke up a mini conversation, sayin hi, and how r u? he was really nice, but i need to work on eye contact. sometimes i think I shut out any potential chances he might have to flirt cuz i avoid being around him a lot, sometimes i am too embared to look up & pretend i do not see him. something tells me i am giving mixed signals, I havent taken any risks...
