Should i feel offended/pissed off if....?

my crush seems to be really uncomfortable being near me, and refuses to look at me when really close, also hugs everyone goodbye except me and my friend who was next to me, and then a couple of days later IMs me and starts a normal conversation as if he didn't even act weird or anything? oh and over msn he reeled off what i was wearing on that night and made comments about my appearance i.e saying i seemed different, looked emo etc, but the thing is i swear he didn't even look at me at all. huh? =/
