I am 12 and they probly would freak out
How old are you? Would they freak out if you told them you did?
My parents don't know I have a boyfriend
Well, have faith that what is meant to be will be. It is hard to have a long distance relationship but they happen all of the time. You stay in touch via phone/text/computer and see each other when you can. I went to a different highschool than my boyfriend for 3 years. You just can't get caught up in drama like wondering what he is doing all the time, etc.
And you need to go about your new school by doing the best you can and getting involved. Have a full life where you are at and it will make you a better couple with your long distance boyfriend. You'll have to trust me on that----- but having friends and activities and doing well at your coarsework makes you more desirable to your boyfriend (and happier too).
Good luck and be patient. Time will tell what happens and you can't rush time.
Do you parents approve of you two? I ask because if they do then maybe they will consider letting you two spend some time together. At the risk of sounding corny, you could keep in touch by letters. I know emails are the thing but letters are just so much more personal. You two can keep in touch via the phone and text messages. You can also make arrangements to meet up. In time things will feel better, change can take some getting used for our minds and emotions especially but it does get better
