so i just had the talk with the ex. fully.
tl;dr
i asked her if she had no feelings for me. She couldnt answer.
I asked her if she broke up withme because of the lies she heard, she said yes.
I asked if she now finally believed what im saying, she said yes.
She asked me if I knew she was still with her bf. I said, I yes I dont care, he never cared when he and her bff were spreading bullshit so we could break up.
She told me, she needed some time.
As far as im concerned, she believes me and she still misses me. I guess all i can do now is nothing.
