Need Help On Marriage Related Question

Hi 2 Months ago I got married to girl whom I knew for last 3 years. actually we were in relationship and somethings happened between us and because of my stupidity I got emotionally blackmailed by her and she had also given me suscidel threats, I decided to marry her but now I realised that was the biggest wrong decision I made, as I am not happy in current situation. Since we got married I have been keeping her at her parents place just for passing time and now she is saying I want to stay with you and live with you, but I know we are not gonna get alone together as our relationship was not healthy at all. now she started more threats like she will go to Mahila ayog and all, can anyone advised what steps should I take ? and One thing is for sure I dont wanna live with her and I want to get seprate from her.
