I know this is not what you want to hear but, if your relationship is as strong as you think it is, your boyfriend will be content with contact via letters, email, telephone, etc until the time comes when you can be together.
You are just a child although you feel as if you are an adult, be patient and just live your life as it pans out.
No you are not wrong for wanting it; but your parents know what's best for you at the moment.
The years pass only too quickly, try not to wish them away.
