Help

So in school, me and my bestfriend were like the famous duo of our year group until about December, when we let another girl join us. Lets just say that was the worst mistake ever. From then til April, she constantly tried to split me and my bsf up, tried to get us to do things like smoke etc (we're 14 and abt to finish year 9), lied about absolutely EVERYTHING. So in May, we reported her to our teacher bestie and told the teacher everything about her. According to the teacher, this was very concerning so she reported it to our head of year. The girl was constantly being taken out of lessons for her worrying behaviours, but she acted like she didn't care. She still remained friends with us, even though we heard from other people that she knew we had reported her. She only very subtly brought it up and never rlly mentioned it directly to us. She then went on holiday for 2 weeks abut a month ago and me and my bsf realised how good it was to be without her again. So this week, we completely ditched her. There was no point in holding onto this fake friendship (She literally tells other ppl about how much she hates us, and talks sht abt us all the time). In all the lessons I sat next to her, I moved away. We didn't talk to her. And even tho she doesnt like us, it angered her so much. So she started making up LOADS of fake rumours about us to get other people to hate us. Loads of ppl in my class already hated her, so a lot are on our side but she has also got loads of people on her side. She has victimised herself and made it look like were in the wrong but were not. And the people on her side are proper scary and are the 'popular kids'
Any advice??

Hey,
coming from a student who just finished year 11 I am all too familiar of being the subject of many many rumours. From what I've experienced rumours last about a week maybe 2 weeks. I know it hurts to have false information spread about you but most people will soon forget about it and then find something else to gossip about. It's just how life works unfortunately!
About the ex-friend situation I think its just best to ignore her until she gets bored. Just continue to ice her out and act like you don't care. Hopefully she will soon be fed up
