Goodbye Letter to Disloyal Friend

Dear {Recipient},

I recently heard from {friend} about how you {describe betrayal}. How could you, {Recipient}? We were friends! I can't believe that after all we've shared, you would go and betray me in this way. I guess you really are a backstabber.

I've gone ahead and told all of our mutual friends about this little incident. Everyone is as disgusted as I am. They all can't believe how horribly you would behave to a friend of {number} years. I doubt any of them will ever wish to see you again, given your behavior.

Please don't contact me. I don't ever wish to associate with a pathetic friend like you ever again.

Sincerely,

{Sender}
