Reply to divorce notice

My husband has sent me notice seeking divorce on the basis of 1. that i did not perform any DUTIES as wife 2. tat i have extramarital affair with my friend 3. that i am not having intercourse with him 4. and extreme end that i have abhorted twice without my husband's knowledge I am not clear about the duties part but the rest is complete bullshit. Actually i want divorce too but i cannot accept all these nonsense. i want it bcz he has abused me mentally physically to the extreme. he tried to kill me (out of anger of course) for past 4months i have been living separately .recently he came to my residence fully drunk and started abusing me aloud and told the neighbors that i was staying illegally (here he meant illegal as without his permission) and my character is bad so i must be thrown out that place..he threatened to kill me and acid attack...he threatened that he ll stick posters about me that i am a prostitute.. it was night 10 o clock i called locaal police but they didnt come. they jus called n asked hows t going..next morning i registred complaint. the police inquired after 1week..he narrated whatever had been bothering me..against me...the police was doing counselling to me to adjust with my husband...that i shud be careful with male dominated society and live with my husband....that inspector justified whatever he has done was out of anger and depression and told me i had not been a good wife.. so he can kill me out of anger or if simply drunk too.. now i dont want to continue this marriage life bcz my safety and sanity is important for me ..more than my married life.. how do i proceed?? how do i reply???
