So, a while ago one of my friends messaged me saying I shouldn't trust one of my other friends. Well recently, the friend the conversation was about read it and told my other friend. Now the friend I was having the conversation with is mad cause they think I told them and now no one will talk to me
I need some advice

Find new, less dramatic friends. I'm surprised that a friend doesn't believe you.

Are these the same friends you asked about in December - https://www.askmehelpdesk.com/teens/ditched-friend-720359.html
