I LIKE THIS GUY!!!!!!!!!!!!!!!!!!!!!!!!!!!… HELP!!!!!!!!!!!!!!!!!!!?

so theres this guy in my school i really like, tall, blonde, and blue eyes, and he has been texting me a couple times, and each time asking me who i liked. i never answered with him , always saying idk. every time he would say me a little bit. then he would ask if i had to like someone, and i would say him. we don’t really talk much during school, only text. i texted him last week, and again he asked who i liked , i said im not sure hbu, and he said this other girl in my grade. i was completely heartbroken. the last time i talked to him was today just to say happy easter. i want to text him again to let him know i like him, since were not going to the same school next year. i dont want to sound annoying though. i hear the girl he likes likes him back, and are planning to hookup. im not sure whether its just a rumor. what should i do ?
