I need help please I don’t know what to do 😭😭

Ok so I really like this boy in high school and I’m in middle school but that doesn’t really change anything bc is going to the high school next year but anyways. I really like him. I think he is sooo cute and funny and we love the same music and we like a lot of the same things and he just makes me smile so much. But the thing is he’s my best friend u know? So idk what I should do. I sent him a text anonymously and he read it and posted it and said slide up I would like to know who but I’m to scared bc Ik he doesn’t feel the same way and I want him to know before he moves bc he is moving soon but we were also talking and he was like yeah I’m either moving soon or when I get out of high school then we were talking about how I could like move with him and idk it just made me think. And another thing is which Ik it’s going to make me sound weird or whatever but I have like body shame and stuff and that’s kinda one of the reasons I’m so scared bc what if he likes I’m ugly 😭😭😭😭so please send me advice 🙏🏻🙏🏻
