IDK What's Wrong With Me

Hana

So I'm a senior in high school now (👏🏼) and there is this guy that is in the same grade as me and I've had hardcore feelings for him sense 5th grade and I have no idea why. He figured it out when we was sophomores and had the same class and had to sit beside each other. He will talk to me off and on but always wants to hook up when he has a girlfriend but when he's single he just wants to talk like friends. It confuses me and hurts at the same time. I've been trying to get over him for a year now and I'll convince myself I'm over him then he starts giving me attention and staring at me and listen to me when I talk in class and I just want to get over him and move on with my life. Please help me!
