誰にも言わないでほしいんだけどって英語でなんて言うの？

You could simply say "Don't tell anyone" and "Let's keep it a secret" at the end. When people say "Don't tell anyone" they usually add "but" afterwards.. For example: "Hey, don't tell anyone but I like that girl that sits next to me in class" "Hey don't tell anyone but I just bought a ticket to go to Egypt this summer" And you could also say "Just between you and me...." and add the secret to it like: "Just between you and me, I stole a bag of chips from the convenience store" "Just between you and me, I bought a new play station 4 for my brother's birthday"

When you explain that a matter is private, your friend should already know that you do not want the information to be shared with others.

Saying "this stays between us" is a casual expression to use with a friend, while "this is confidential" may sound a little more formal, but is still used quite often.

A "I want to tell you a secret but it's strictly between you and me, OK?" B " Yeh sure. You can always rely on me to keep a secret." A " But seriously, don't tell anyone. Do you promise? B " Of course. I'll keep it to myself. So tell me, what is it?"
