Am I the Jerk? Need Advice on Friendship Drama

So I need to know if I am in the wrong for a situation that happened last night because I'm worried about it.So keep in mind something happened before all of the drama .So I came to my friends upset.They started trash talking the person and then my other friend claimed this person kept bugging them. We ended up not being able to proof anything but I guess it wasn't over because they decided to take my role away in my friends server because I told my other friend I was trying to find dirt on my other friend.It was kind of like a joke between my other friend and I because he told me I wouldn't. Anyway because of that and because I yelled at them they told me I was being disrespectful.But I was told that we would talk about it tomorrow on the phone with a other friend.But I guess they decided to go behind my back and talked to the friend without telling me.So yeah they all think I'm a jerk. I made them more angry when I left the server after I told them that they shouldn't have done that because it was outside .But I need to know I need to know if i am in the wrong? (Keep in mind I was told that my role was not going to be taken away the night before )
