PLZ HELP! I know my teacher likes me but....?

I'm 99.9% sure my teacher likes me (i'm in college). I aint going into the silly-flirty details. I'll get to the main point now, that I RECENTLY found out he's MARRIED. In student emails he sent me youtube clips of he on the guitar and once had a label. i thought they were good so searched for a music page on MySpace. Since, he sent messages on there that wouldn't be school like. I was enjoyin it and startin to like the guy but i found out he is MARRIED. I made a joke about liking him on the guitar (and i do, but sent it before I found out) and wondered if i could find him on frostwire. he said no, but sent me a MySpace message about making a copy for me. NO one else in my cl knows he plays the guitar or any of that. I was startin to think I kinda liked him but since hearing he was married I've been flipping out. (Unless he has a bad marriage) My friends are telling me, I shouldn't have added him on MySpace, but I idn't know he tied the knot concidering of his flirtyness. I just saw it hadn't been for like 8 months that he's been on there but found out I had one. He's a good teacher. I only have 2 more cles it being a short cl but he on my page, Idk whats next. What should I think? What should I do?
