He obviously likes me, but I texted him to deny it.

He's right. He doesn't care much about you. I am a man, and I understand men's psychology. If he really likes you, he won't be stupid enough to deny it when you ask him. You should know that the consequences of not admitting it are fatal. At least, to be sure, his feelings for you are just a little like you, but not love. It's best not to take the initiative. Girls' reserve can impress men more. Forget all this, wish you progress in your studies, and wait until you get into college before falling in love.
