Divorce

I got married in december 2014. It was arrange marriage but i know the girl since childhood and before marriage we were in a relationship. During the same time i was diagonsed with anxiety and depression. I informed her that i am getting treated for it. Our relation had moved forward by then. But slowely she started ignoring me and we had frequent fights. But still she wanted to marry me. After marriage she refused physical intimacy saying that she wants time. So i told her that i am still in treatment. She felt back stabbed and left me in first week of jan. Since then we are not in touch. The only thing she wants is divorce. She even returned the mangulsutra and other stuff. But i love her a lot. Please suggest something. She is a lawyer. I dont want to loose her. We are family friends since 20 years.But she and her family dont want to listen. Can counciling help? Please reply. She has filled a case of nullity of marriage against me. Can counciling help my marriage? Can i save it? I dont want to loose her. Please help and suggest some way.
