She said she hated texting a little. What should I do?

This kind of reaction of girls is basically rejecting you. You don't talk much, which means that she doesn't have many opportunities to get to know you and like you, and you probably have nothing in common.

If you don't particularly like her, I suggest you give up. Always pestering will only disgust girls. If you really like her, wait for the results of the college entrance examination to see if you can get into a city or even a school. Then, from time to time, ask her out to dinner in the name of a high school classmate, or chat on qq. If she is willing to have dinner with you, it will be more hopeful. If you are admitted to a different city, it is still recommended to give up. High school couples break up at different universities, accounting for the vast majority, not to mention that you haven't started yet.
