Is this our fault this is happening?

So my friend mary asked my friends brooke who iss your best friend but brooke didn't wannaa tell her because mary would be upset . so basically brooke told her that her best friend was Jodie ( me) . Mary said Jodie and I sed Brooke so after that mary got upset and grumpy saying that we lied to her and stuff soo we jst didnt say anyfing coz we didnt want to start any arguements . soo mary went off with casey and chloee and brooke and i jstt went together . she was then ignoring uss but we didnt care.When i was with brooke we had fun and we didnt miss mary buyy she missed uss . soo 2 days later she started to beg us sayingg we hated her and that we made her go wiv casey and chloe, that we wouldn't like it if that happened to us and making it feel like its our fault soo she kept on sayin tht she misses us. But brooke sent her a text saying I said im not makin u hang rand wit kc, and i didnt say i hated u , ur just makin things up, and i wernt ignorin u! Everytime i tried to tlk to u u ignord me...so.. :/ ... soo did me and brooke do anything wrong .... btw me and brooke are fed up wiv her coz she wants everyfing her way and stuff.... and 2 days ago wen chloe and casey had to go to a school trip at lunch and brooke wasnt at school. mary started following me asking me if i could hang around wiv her and stuff so i said kayy she only did that coz her friends wernt there and when brooke was ill on that day i went to hang out wiv my other mate hannah and she asked us if she could join .... x do you think she was using us . And at the moment we arnt friends wiv her and we dont miss her at all .
