I like a boy, I'm not sure if he likes me back and it's getting stressful?

Right now, I have the BIGGEST crush on this boy, I am literally in love with him. We’re Game Pigeon buddies, meaning he’s one of the only people I can get to play Game Pigeon with me. He has the biggest, most beautiful brown eyes I’ve ever seen and his hair is absolutely gorgeous. And whenever he looks at me, it’s like time is frozen. I’d do anything for him, but I’m not sure if he’d do the same for me.

However, on Halloween, my friend, got a text message from him. A few weeks back, before he was grounded from his phone for two weeks (he was suspended from school because his friend peer pressured him into doing something). She had asked him to be my boyfriend. He said, “I’m talking to another girl right now, so no sorry.” then he sent another message saying, “but we’re friends rn.” However, we are unsure if he actually IS talking to a girl because sometimes guys just say that to make girls jealous.

But, in homeroom where we do our homework and sometimes tests and things, I ALWAYS find him staring at me and smiling. And he acts differently around me than other girls. But I’m just a teen so what do I know?

But what if it’s not? I’ve taken so many quizzes, and looked up so many things about it, and they all say that he’s crushing on me, but how can I be sure? HELP
