easy and straight answer, NO!

hello Carina It depends what sort of secret and if your friend is concern by it or not...

If you tell your friend a secret, it is an open secret, the secret is not a secret. If it is not a secret, you can tell your friend(s).

Be careful, your friend may not be your friend forever.

secrets always should be secret for a normal person.....but for a true person...nothing like secret
