Section 31 ham at Jammu and Kashmir

Hello sir....I got married in Nov 2005 (girl from Jammu & I am staying in Delhi) In the very first year of marriage, we were blessed with a male child. My parents and other siblings never stayed with us in Delhi. I filed divorce in Jan 2008, which got transferred from Delhi to Jammu in the year 2010 but never contested from Jammu by me. We had a patch up in year 2012 and even I stayed in Jammu and invested Rs.25 lacs in his fathers business (I don't have state subject of Jammu, so in construction business I used my father in law license but in his name) I have got the transactions showing money deposited in their bank accounts, which my in laws denied to return back and even I thought that it is ok if child is with her. (I never filed criminal case against my money) I can prove with various communications happened with the PWD department that I was handling work moreover when I moved from Delhi to Jammu, I resigned from my private job. After staying in Jammu for around 11 months, I came back due to my wife's attitude and she declined my accompany. My wife got expartee divorce in March 2015 and today I received notice u/s 31 hma from Jammu(I suppose it is permanent alimony) Even she was granted Interim maintenance which I paid her before divorce but when I came to know about ex partee divorce, I stopped the same. Even I don't want to set aside the case and I don't want to stay with her anymore or carry on with the matter, as I have to settle my family life soon. My son is with him age 10 years for which I am going to file for visitation and custody. As only son of my parents, I was not able to proceed with the same in the past, as my mother is and was in critical condition and on dialysis. Since last two years she got hospitalised 4 times (In BLK Hospital, AIIMS, Jessa Ram) and in a very critical mode. Can I fight back against alimony that she is staying in Jammu since last more than 7 years (continuousally) As can I explain in court that when she took ex partee divorce, I also never tried to reply back as why to fight and waste time when other one is not willing to carry on with the relationship. It was my parents retirement money which my father deposited mostly from Punjab but since last more than 4 years they are staying in Delhi and even we have our Aadhar card, voters card of Delhi. As a senior citizen can my father and myself combined can file criminal case from Delhi (I don't want to file civil suite) Kindly help me out with your best possible remedies. Also not regularly but for few months in between I worked with different companies and left job due to my mothers ailing condition. (I have almost nothing in my name like property or other assets, it is all my parents hard earned assets and in their names registered.
