How do i tell a guy that i like him?

okay well i'd just be like i really need to talk to you about something, and when he's like what, be like i really like you and i have for a long time, and i couldn't hold it in any longer. then you'll find out if he likes you back. if he stops talking to you, then you'll realize that he's not worthhh it &you'd be wasting your time anywaysss<3
