He Lied to me ... I just dont know if i should tell this person, is it the right move to do?

My friend codey has lied to me, calling me his best friend and stuff... Then yesterday my friends came forward and told me that he thoguth i was a s-lut and that im annoying and i have a bad personality. He told me he NEVER said anythign bad behind my back... I dont know, my friend told me she was not supposed to tell me there for she does not want talkign to him about it, But in order to prove my point.. what do i do ? i dont want to do this to her, but i have to talk to him... help?

talk to him just dont reveal your source and if he tries to be mad at him turn it bak around to where he's the one at fault

talk to him and make him feel bad about it and u thought u could trust him. you ahould talk to him rather then not tellinghim cuz u dont want a fake friend.who nows maybe your friend thats a grl is lying.just find out which friend is fake and which friend is fraud.

How well do you know him? Remember, people will say things to mess up a good thing so they can have it for themselves. Sometimes people are telling the truth. It depends on how well you know these people, and can you tell which one is lying.

You can bring them both face to face and find out what the facts are, the one that doesn't want to get together and figure out whats going on, is usually the person lying, why would a person not want to clear their name unless there is something to hide?
