Help me

My husband doesn't provide me any information about his work, whereabouts, finances, family or extended family or relatives, he wants to end the marriage however bcs he was a divorcee at the time our marriage (first divorce by mutual consent ) and seems to have patched dupari with ex as he has a son from first marriage and the wife earns well he acts determined to abandon me, in spirit head done that already, forcing me through coercion and isolation, by not providing expenses for household or healthcare he wants me to end the marriage by mutual consent. He fights for divorce, doesn't allow me to conceive and refuses any accountability to wards the marriage and my rights as wife. His mother and others cut all contacts with me and only thing is my husband still stays in the flat owned by his family which is my matrimonial home. I have not privy to any of his routine, life events, earning, finance, liability, social standing etc. he doesn't even let me call him to ask when he will be returning home, fights on petty things like why I didn't open the door quickly or put why I rolled 6 chapatis calling it wastage of food . He himself doesn't eat with me, stays outside most of the time and return only as formality of owning the home by his mother or family. His lifestyle is pretty good and his spending might cross 50-70k a month. However he does provide me even 5000 for grocery saying I am teacher and earn enough to buy grocery for myself. What I can do to deal with such a tactically led in laws and husband who is eager to be free of our marriage against my will to continue it just bcs his ex wife pressurise him regarding access of 11 year old son saying she will let him enjoy fatherly bliss ,access not until I'm there as his wife in life. I have no evidence of their indulging beyond co parenting as he has totally been opaque about his every little and big thing from . More over blames me, give me guilty and puts allegations that are baseless like I married him to be a baandgul(saprohyte) , he refused to take responsibility of fatherhood when I was pregnant and forced me to abort it saying we will plan again in future . However it's been two years even on asking he refuses to agree conceiving or having baby with me. Now he is upto forcing me to vacate flat by shifting me to 1RK saying any excuse to remove my stay at current residence. What should a woman in place deal with this legally ?
