This is a mess

Ok so there’s this guy we’re really close friends. I kinda have a crush on him. He is super sweet and funny and nice and cute and smart. So the other day was home coming at my schools and us and all our friends went we ended up dancing towards the end bc we’re friends so people started joking that we’re dating or should date or like each other. I haven’t told anyone I like him not even my best friend and she’s like a sister to me. He is also really close with my other friend she has a boyfriend but she’s still really possessive over him so she started a lot of drama over him and I being close. Bc if that I don’t really want to tell my friends I like him and the fact that his friends are my friends and I don’t want him to find out. He is amazing and I’m just not I don’t think her likes me back but I don’t know he likes someone. He and I were talking about it on video chat only me and one other person know her likes someone and that person knows who it is but I don’t. And earlier today he was making a bunch of jokes about us dating bc our friends do that so we just beat them to he punch line and now I just can’t stop thinking about him. What do I do? There is so much more to this story but this is the short explanation.
