How to make a highschool relationship last

I 17m am dating 16f, I finish high school this year and will be going to university in the beginning of next year. We want to stay together and plan to regularly see eachother. But it is uncertain if she will attend the same university as me, is it possible to make this work long term?

Edit: The probability of us attending two separate universities but in the same city has now increased meaning we will be able to see each other regularly, does this increase the chances of success?
