What next

We married in 2009. have two boys now. since 2011, i became a victim of DV. my inlaws and husband broke my relation with my parents and we moved to a different city in 2013. When i couldnt take this DV anymore, I met the local police station where i was advised of 498a. That was done, husband and in laws were called..and expectations set - i would be living separately with my kids and they would have visiting rights.. a maintainance of 5000 would be given every month to me and i would not be physically or mentally torchered or any relation kept hereon. since that day in 2013 we were separated and met in some public place with kids..Gradually I started talking to my husband to get things sorted so that we could live together again if he would promise not to beat me or torcher me. he refused to change. meeting was no more every week and they preferred to call and talk to kids.. that also stopped from 2015. there was no contact between us since then.. suddenly once in 2016 feb, my dad in law passed away.. husband called me. and thats when we met for the last rituals..so approx 3rd march 2016 we last spoke. then on.. no contact..we do not know each others whereabouts and dont know whats next. staying with him is not possible now with whatever happened.he never took me to his native relatives place that i trace him now.. i dont know any place where i send any notice or contact him whatsoever. maintainance has stopped since mid 2014.. from the time i tried getting him back. he said he does not have income so cannot pay for a few months.. and that never came since then. i am somehow running my kids education and household with my salary. no help from anywhere. although now i have brought back relations with my parents but no help from them either. i feel completely helpless and clueless now. i dont know..what i should do next.please help.
