Brothers best friend

So, I have a problem. I've known my brothers bff since I was a baby, but not since maybe a few years back did i start getting close to him. I'm 13 now. I'm super close to my brother he's probs my bff. So anyways I started getting closer and closer to his bff, and maybe about 3 yrs back I started getting REALLY attracted to him. He's just so kind, funny, super hot, and he listens and understands me so well. Well somehow the topic of me and him being together came up and My brother acted Sooo grossed out by it, it practically broke my heart. I just like him so much but My bro acts like its the grossest thing ever in the world. I don't know what to do!!! My brother told me that my crush has liked me but he doesn't know if he still likes me. I think he might not sure. If he does it makes me happy but at the same time it kills me because I know That my bro doesn't like it. I'm so close to him that I don't want him to be grossed out, but I just have no fucking idea what to do. Help! 😫😫😫
