I understand your feelings and that is a huge bummer. I’ve only known one couple out of all the people from my class (I went to art school so it was easy to know a class of 200) who stayed together from high school to now. But, who knows how it’ll end. Maybe try and pick up a new hobby like guitar or a sport to distract yourself. If she’s gonna focus on school then you shouldn’t dwell in between the silence. If she’s experiencing and trying new stuff in college then you too have to keep evolving as a person. I think it’ll make the distance easier for you and ultimately make you a more interesting person. Especially this young you can try and throw away so many hobbies and be good at all of them.
