How to get him?

So there’s this guy in my class since 7th grade, we’re now in 10th. I’ve liked him all this time, even while dating some other guys. He has rejected me once, but I wasn’t pretty or smart that time so I don’t mind it. We’ve totally got over it now it’s been a year. But now, we’ve started our holidays ( for exam prep) and will only come to school for exams until feb end. After that our finals, and then we go into diff schools. I don't know how I should get him if we won’t even meet irl. And he’s a really bad dry texter on chat until it’s the love of his life or sumn. Pleaseee helpp I want him to go to prom with me by jan end.
