My Group of friends broke up? Was it the right thing to do?

I have this group of friends and we all love each other so so much. We are practically BEST FRIENDS. There are Two guys in the group and 3 girls. Lets call One guy A, And the other B. Now for the girls, We'll call Girl one C Girl two D (I am also a girl so i dont have to mention myself). we had no problems UNTIL this year.We are all becoming freshmen, entering that high school life.One day, C just kept getting mad at us for no reason which really pissed me, D and B off. C would get mad at us for doing the most simplest things. For example, Us pranking each other. We always do that and she was always okay with it but now she just flips out. And A is always on her side.C and A are like friends with penalties because they are together ALL the time and really really good friends. They're practically on a whole new level than Us. But one day, we just couldnt stand C anymore because she would go on saying she listens to us but we never listen to her.She compared us to A,Telling us that A understands her most and that A has never ever made her mad her whole life. At the point, B and D decided to leave. I also decided to leave but inside something was telling me this would work out. Fortunately it didnt and now we've broken up. B, D and i are in our own groups While C and A have cut ties with us. I've tried explaining to both sides but it just wont work out. So, maybe it's best to forget C and A. My question is, Was it the right thing? Or should i have worked it out?
