If you want to be with her, I think you should wait until after her college entrance examination. After all, delaying her college entrance examination may delay her life, and you don't want to do that, do you?
The college entrance examination is over, see which city she has been admitted to, is it far from you? If possible, work in her city. Long-distance relationships are hard. And in college, there are many excellent boys, and you have many opponents.
Let me cheer you up first and tell you something about myself. My boyfriend and I met after the college entrance examination (he didn't go to college), and then I went to other provinces to study in college. Later, he came to work here, which was very good to me. We have been together for more than three years.
