Confused and need helps

K so there's this guy I like. Let's call him Nate. We r really good friends. But my BFF likes him too. Lets call her Isabelle. I have a lot in common with Nate but Isabelle doesn't. And she isn't really good friends with him. Idk if he likes me but all he said about Isabelle is that she's kinda cute. But Isabelle would hate me if she knew I liked Nate. Nate doesn't know I like him. We like go to the filmes and hang out all the time but Isabelle doesn't know I like him. And I really don't know what to do.
