How do I break off this friendship?

[Tony]

Okay. This guy I was once friends with started hating me. He's a senior and I'm a sophomore at my high school. His reasons were pointless, that's when I realized how pathetic he was. But my best friend continued being friends with him even after he would talk shit about me on Twitter for everyone to see. I let that slide, it bothered me that my own best friend since KINDER would still be friends with someone who is doing this to me but I left it alone. Finally this senior and all his stupid friends kept telling me I was gonna get beat up. So this senior cowardly hits me from behind one day at lunch and before I could fight back the teachers were already at my side breaking everything off. I asked my "best friend" if she was still gonna be friends with him. She said "No, he's a pussy for doing that. I don't like him anymore." Well they've still been conversing on twitter and I just saw them today walking in the hall together and she completely ignored me. I was beyond done when that happened. I feel so betrayed after telling her numerous of times to break off their friendship because if she was in my position I would've done that. I saw her today and ignored her and her friends have been telling me that she's sad because she thinks I'm mad. I'm not mad, I'm done with her. How do I tell her I'm done? I want to sound confident, no mercy but not rude or mean. How do I tell her?

just tell her what u think like "listen _____ i cant believe your still his friend after he hurt me and has been bullying me. I know i cant choose your friends but if ur his friend i cant be yours anymore. So you have too choose between me or him" and if she says him than just say ok fine this is good bye and u have always been by my side and now were done. And say something like " i loved having you as a friend"

I HOPE I HELPED

(I'm not mad, I'm done with her. ) At least You are clear about your feelings and you seems smart so tell her i am not mad at you but done with you and then you will be really done

The best thing to do is to really just be upfront and straight about it. And if she had any feelings for you as a friend she'll be upset and say she won't talk to him anymore, but obviously that's not working, so don't let her quilt trip you. Good luck! You're definitely doing the right thing! A similar thing happened to me, except I didn't break off our friendship then. It got progressively worse until i couldn't STAND to be anywhere near her, and then breaking our friendship off became very ugly. Good Luck
