She ghosted me suddenly after a long term relationship lasted for 3 years.    
I tried many times to have a convo with her, but she is refusing to have a single talk, she started to add my old male friends and come back to her old male best friend which she always said that she don't want him in our life when we were couples. She used to love me so much, but now she is being sleazy and I hated her !
There isn't a third party intermediated between us, I just wanna anybody to help me, to explain her that I wanna only talk to finish my 1 years depression after she left, just to understand why this happened, I have many qs and I can't move on till I get and answer. Just WHY ! pls someone.
