Mental torture by wife

Things are going tough i live with my wife along with my parents who are dependent on me, my wife is ill treating my parents and me. In the past i had out of emotional instability slapped her once to which she too had slapped me back and had instances of verbal abuse both sides but she uses now that against me for every argument. She is not willing to resolve things she just boasts feminist ideologies for not adjusting and acuses me of forcing her to do adjust. The slapping instance is two years back whereas verbal abuses used to happen three years before which she uses now also we had a year long not having sex and later had sex just because she wants a baby and i am not sure is it also to use against me as there is no affection and care nor physical interest during other routine days or hrs. She had told to her parents that i had slapped her in front of my parents and that they have encouraged me for being dominating whereas this behind closed doors which later my parents were told by her. I have asked if she really want to be separated and go for mutual consent divorce but that was never given a proper response and is always responded bad. I have no clue where my marriage is heading if there is a separation in future i dont want my family to suffer or accused as they have never intended or did any action bad to her.
