Why do you depend on him?
From what you said, your boyfriend doesn't care much about you. If he doesn't care, he won't care.
You just need to arrange your life and future.
For example, my own postgraduate entrance examination or other work-related things.
So what if you can't get into a public school? People in public schools just sit still and have no energy.
It is better to give full play to your abilities, and you will create your own world in the future.
