<human>: My friend of 11 years and I have gotten into a fight and this is the end of our friendship. He's dragging the rest of my friends down with him and I'm going to be alone in no time. Please, I need help.

**Background**: I'm 16 years old in high school. My friend and I, who we'll call Tristan, don't get along at all. We have grown apart so much that it's almost impossible not to fight with eachother. He's friends with all of my friends and I see him daily in every one of my classes.

We got into an argument that started out with something silly and now its gotten ugly. Neither of us are right for what we have said, but honestly, I have been waiting for this to happen. I really dont like him and the only reason I have tried to stay away from fighting with him is because he's friends with my friends.

The issue is, now we are arguing and saying nasty things to eachother, and he's airing out our dirty laundry to everyone. I already don't hang out with that many people, and he is making my friends feel uncomfortable around me. I'm beginning to worry that theyre going to stop talking to me simply because he's talking crap about me behind my back when I'm not doing the same to him.

I don't know what to do reddit. Please, I need your help. What do I do to keep my friends?

<bot>: Me and an old friend got into a serious pissing match and now he's sharing our texts and conversations with all my friends. My friends I think are beginning to feel stuck in the middle and uncomfortable. What do?
