Am I Cheating?

i've been chatting with this friend for couple of days now thru facebook. and i'm enjoying it. the catch is that he's not just a friend to me. well, now yes, because i'm in love with my sir. but i used to have a deep feeling towards this friend. and i would be proud to say that he also liked me before.

but our "relationship" never progressed. we stopped at being just friends. but everytime i chat with him online, i can't keep the smile off my face. he still sends shivers to me, even though he might be eyeing someone right now. i just want to enjoy the moment.

however, i'm not sure how my sir would react once he learns about this. he always knew we had "something". am i already cheating?
