Did he like me, or was he just a bully?

When I was 11 and in 6th grade six years ago, I met this boy, JL. I think he used to like me because he'd always find an excuse to talk to me, or sit next to me. He always had to be next to me in line, would blush a lot around me, etc. I hated it because, me being the insecure freak that I still am, was afraid of being heartbroken. Plus, he was too young looking back then. Afterward, when he started his growth spurt in 7-8 grade, he began to tease me because of my old religious beliefs. He only referred to me as "Hallelujah," never my actual name. He'd ask all of his friends to do the same. Even outside of school, like when we'd bump into each other around town. When no one except his best friend was around, he'd comment on my body and how he liked it, but he'd still always be mean to me. Now, we're both seniors in high school, and I'm beginning to develop a crush on him. Except, now he doesn't even pay attention to my existence. Maybe he never liked me and just liked making me uncomfortable? I feel very jittery around him now, and it's rather unsettling. He's my neighbor now, too.
