Horrible situation

So in class today me and my friends were working on something in a group. The main characters are me Natalie Terran and Antonio. So Antonio gets picked on a lot and my friend Natalie hates that. It was Antonios turn to go but when he went he messed up. So Terran starts yelling at him. Because of that that made Natalie start yelling at Terran. Terran just backed off n was shocked I guess at the time and Natalie got really mad outta nowhere. They were both my friends so I decided to stay out of it.

later on in the day I got a text from Terran saying how mad she was from what had happened( she wanted to talk about Natalie)N I clearly explained I'm not finna talk about her behind her back n tht I'm not taking nobody side cuz they were both my friends. She replies and say how I was fake n that I shouldve protected her n that I was just so soft n a horrible friend like... Outta nowhere. In my perspective I don't need anyone to protect me so neither should she n im not her mf protector😂 she kept going on about how I let her(Natalie) be a voice for me like GIRLLLLL no!!🖐🏾she always find a way to blame something on me or always mad at me...Am I in the wrong or is she?? I thought I did the right thing but apparently not..what do you think??
