How do I confess to someone I have known for so LONGGGG

*tw lots of swearing and may have sexual things included* So my friend and HIS IS LIKE SO HOT AND CUTE ITS LIKE HE HAS A SPELL ON ME but I really like him like I mean by for years and I can’t keep it in I really want to let him know but I don’t want to break our friendship and it’s hard for me to keep in cause there’s this girl he has been talking to and I FUCKING HATE HER SHE A PICK ME LIKE URGH and she’s been clinging him and it’s making so mad and I know I’m jealous but I HATE HER LIKE FUCK YOU . It’s something I don’t know how to control I literally have secondhand thought about confessing but just couldn’t . But one thing is that were in the same class but everyone even my teacher is just disrespecting him like he’s human too not you little toy and it just pisses me off. I’m too lazy to like change the topic this is how imma do it :). So I had this dream where I actual confessed and we made out that I felt like I had a whole swarm of bees and butterfly in my stomach that idk how I just became horny and to clear if I said I like him I love him but it’s making feel like he’s pushing me away and I don’t want to force I want him to genially like me not some forced love
