Why is this guy and his friends only mean to me?

Anonymous
There is this guy who knows I like him. He glares at me. He tries to make me jealous. He makes fun of me behind my back. He tries to appear in front of my eyes but ignores me. He gives me one word replies when I text him. His friends ignore me too. His friends talk to my friends and follow my friends on social media but never me. I feel like whenever I put quotes about love or sadness on instagram this crush of mine sends it to their friends. Because there is a huge gap of timing of him watching my stories. Now I hate him a lot. But what is the reason guys behave like this with girls. If he doesn't like me back why can't he just ignore me. Why does he glare. Why does he do all this.
