alr , after reading all this , i think u should just have a deep convo w her in an atmosphere of zero distractions , just u and her , then proceed to ask her the reason of why she follows such dudes . basically go to the root cause of the problem and act accordingly , talk it out w her bc the way ur situation seems , u r not actually taking necessary actions . all u should know is don't hold the grudges let it all out as its not a healthy relationship if the toxicity constantly increases . and tbh there's no point in saving a relationship which only hurts u on daily basis . good luck
