High school sweet hearts?

Erin • UC nursing
My boyfriend and I will have our 1 year anniversary on the 12 of this month and we're both high school seniors. I'm going off to college but not far at all only like a 4 hour max distance and of course I feel like I will miss him the most!!!!
 I know how mushy/ uneducated about love/ and not ready people can think of high school couples, but him and I both only see each other in our futures. What do I do about our relationship!! I don't want to loose him and have even considered staying in town for college so that we can live together..
 I know that I should follow my dreams for school, but what if my biggest dream is to be with him? Then what do I do???!
