Should I disown her

My bets friend just went behind my back and did something I told her not to do and she promised she wouldnt and I found out right after she said that ,she did it any way . How do I make her admitt it with out asking her?

it depends on what it was...

she asked her boy frienda personal question that was supposed to stay between him and I even though it was about her

well it was about her

she still promised

I don't know. did it wrk out? or are you still wondering what you shuld do?

no I never told her I was mad at her I still am its kinda makeing me slowly hate her

then just dont b her friend nemore. I don't know

I would try and forgive her. you should talk to her about it, in my opinion, she should apologize for breaking a promise.
