Let’s see....
You asked him to teach you essentially 4 times in what amounts to a 10 - 15 second conversation. He said no 3 times. I understand your frustration from wanting to learn from somebody you admire as a player and being told "No", but I think asking once, maybe twice should do it. How many times does he have to say "No" before you get it? He may have said no initially because of a lack of time, other commitments, lack of desire or whatever, but I'm pretty sure that last no is just because of your nagging.
I'm sure you weren't just trying to be a pain, and I believe you truly wanted to learn something from this guy, but when you ask for help and it gets denied move on. Find yourself a local established instructor or hang out at clubs and just "watch and learn". I find I learn a ton of stuff just by watching and listening to bands. I don't mean plagiarism and copying songs (unless it’s a cover band); I'm talking about techniques and song structure / compositional stuff. Sometimes what you learn is how NOT to do things, and that can help even more than some of the other more positive things you learn.
Maybe next time you're at a show and you see a good player just ask the guy/gal "Hey that one riff in the third tune was awesome and totally carried that song. How did you come up with that?" This plays up to his ego a bit and he may tell you or he may not. If he does, great! If not, oh well, maybe next time. This way you come off as a fan and a cool guy, rather than as a _______ (choose your expletive of choice).
I'm sorry things didn't go your way, but I can kinda see why. Just don't give up. You'll find a good instructor soon enough.
