No, of course he's not "mad" at you. Some pieces you click (clique?) with, and others no. My teacher tried to get me to learn a few different pieces that I've tried out and then given back saying I just don't feel them. I skip movements in sonatas ALL the time. There's one movement in Mozart's K331 right before Alla Turca, my instructor let me struggle with it for a week and then said it was time to move on.
As far as him saying you don't have time to learn it, I don't understand what that means. Are you in a rush to get somewhere with your playing? Don't take it personally and don't frown.... you may be happier moving on to something else, but you also may want to stick with the Beethovan. I HATED the Haydn sonata I was just learning because I was having difficulty getting the rhythm, but now it's my absolute favorite piece. I only do the first movement, because the next one is above my level.... for now.
What I always do when I get a new piece, whether it's one I've heard before or not, is go to iTunes and download a recording of it. If there's a passage that is not getting past the neurons in my brain, I just listen to someone who knows it well play it. Sometimes I play along with it - which is horrible to hear because their piano is so nicely tuned and mine... well... Not only is this a good reference, it helps build your classical library. I'm making the assumption that you have an mp3 player, of course, but if you don't.... you should. It's so much easier than running to the store to buy a CD everytime you want to learn a piece, and cheaper since you can just buy the movement you want for $1
I say that if you don't hate the piece, then keep working on it. If he's moving you along to the next movement, then go back to this one in a couple weeks. I learn them out of order too. Play to a level just higher than where you think you are, you'll be surprised what you can actually play. And wow... what a feeling of accomplishment that is!
