No you're not wrong.
If someone pressures you into anything you're not comfortable with, it isn't meant to be.
I'd honestly say you're better off out of that situation, you made the effort to work around his schedule to meet up with him. Instead of appreciating it and making you feel special, it wasn't good enough.
Put it down to experience and don't pretend you want different things from a partner just so that you can be in a relationship quicker. It takes time and practice to find a decent partner.2

No, you weren't wrong. Not in the least bit. You can't force yourself to open up to someone, that sort of thing takes time. Even though you had been talking to him all summer, it's different when you haven't actually spent time in person with someone. He should have understood that and been accommodating in order for you to eventually open up to him.
That's not something he should have gotten angry at you for. I would say to just take this as a blessing in disguise. Clearly this guy wasn't right for you since he was so pushy and mean about something as trivial as you being shy. You deserve much better. I'm sure you're upset and that's understandable, but really, none of this is your fault so don't blame yourself.3
