What marvin said. People will come and go. If you two are really that invested in each other you will continue your LDR with your studies. If it’s unmanageable, that might be a sign. There are so many people in this world, and so many people at most colleges. You two could take a break, see if feelings continue after you’ve ‘separated’? I think it could be a good test of time. Perfect love does not fade in four years.
