Greetings

I've been reading this forum for a while and I need some advice for this little problem I've got
I'm with this girl since february, we're both in our last year of high school and we've got our final exam coming up in two weeks.
She wants to go study abroad further on, which means we've only got 2-3 months top of staying close to each other. A few days ago, we met and she told me she wants to break up, since she;s afraid it will be harder to move on if we stick together until she leaves.
I told her she's stupid ( not in an insulting manner) and we should just enjoy the time we've got, then we'll see what comes up. Then, she told me we should break contact until those exams pass, to settle things and decide what to do next. I agreed on it, and decided not to text/call her anymore.
I really want to get this relationship further on,so what should I do next?
