Input: Basically he seemed pretty excited to audition for the first play we did this year, then was disappointed when he landed a role as pretty much a background extra, even though he had the option to quit, he instead chose to continue through with it, complaining the whole time, and being disrespectful to the theatre teacher. A couple of times I got annoyed with it and suggested for him to quit, as he didn't seem happy with it. He continued through with his ways and it got to the point where the theatre teacher talked to me privately about him, asking if he was okay as he always seemed to not follow the stage directions and loudly talk backstage, being rude and giving attitude to the others actors. 

It all seemed to go away until recently when we we're hanging up pictures of the show and one showed a blatant sign that seemed to make a joke of the whole image. I was only a little  bit annoyed, yet our theatre teacher seemed in distress about it. I go in and see him freaking out about it like he's worried he's gonna get in trouble when he has never even been punished, as our theatre teacher is rather elderly and kind. He seems to not feel a hint of guilt about doing it, which made me lash out at him, blunting telling him to switch electives next year as with our next theatre teacher I guarantee the shit won't fly. He looks at me with a shocked face as I walked away, and later in the day refused to talk to me saying that what I said hurt his feelings and was rude. This happened a week ago, and on Monday he called me an asshole, promptly pissing me off to call him a coward for not apologizing.

 I've looked at this from every angle and can't see how exactly I could be the asshole, but I guess I could be wrong. Sorry for the long post.

TL;DR friend was being a dick in theatre, I eventually got sick of it and told him he shouldn't be in theatre, now he won't talk to me and thinks I'm an asshole.
