doesn't sound like a good thing. how long have you been dating? have you ever gone this long without talking? did you have a fight? Have you tried to call/text him? If you haven't tried to contact him you should do so
This sounds bad either from a personal (his own personal life) or a relationship standpoint
Is she dead? Has she dumped me? Is she alright? Did she made some mistake and can't talk?
I would go crazy about it xD
It is normal that you are worried, but it may be so many things that the only solution is to actually talk to him. if he doesn't show up, try to speak with his family (do you know someone of his family? Mom, Dad, Brother, Sister, ...)
He could very well be thinking the same thing. It's like as game of relationship "chicken" where both people are worried that the other hasn't called, and in reality all that's needed to solve the issue is to make the call yourself.
oh wow that would be so nerve racking D=, if you have called him and sent messages (r you sure he turned his phone off or could it have just gone flat?). Then again seeing as how you are under 18 years old I am thinking he likely lives at home, meaning if he was missing his parents would have notified the police and you would think...you. It sounds like he is being immature and just doing the old "shut it out and it will go away" thing =[
