Please every oen answer i realy need advise fast frieind for 11 years hates me for no reason?????????

if she refuses all contacts then thats just her choice you can't make her speak to you when she wants nothing to do with you, honestly if i was in your shoes, i would let it go becuase shes being stubborn and chooses to believe in something thats not true instead of the truth, its her loss, you just have to move on, sometimes youre friends for a long time but theres a ending point in some friendships. you say its easier said then done, of course it is but you still have move on, friends come and go, maybe once she sees you quit trying to help, she will come around and maybe start questioning it
