i’m scared for the future

my boyfriend and I have been dating for 8 months. I love him more than life itself. he treats me so amazingly and I couldn’t have asked for someone better. I am in awe of him everyday and how amazing he is. we are both seniors in high school and we are applying to college. we have the same top college but it is really hard to get into and neither of us are sure we will get in. his second choice, which could very well be the college he ends up at, is in another state. it scares the hell out of me to have him possibly moving hours away to another state. I want him to choose the college that is right for him and I want him to be happy but I can’t imagine my life without him. its many months away but I can’t take my mind off of it. what do I do?
