Maintenance without Divorce for me and my daughter

I was married in 2018 and was cheated into getting married by stating that he is a job holder and he has properties backed to him and more lies. After marriage,I came to know he doesn't have a regular job and always gets fired from his job.I had given dowry and gifts to parents in laws and sister in law. I had a rough phase starting from day 1,I was mentally tortured,brutally harrassed.I was asked to terminate my child during my pregnancy but I refused and gave birth to my daughter in 2019 from then on,I was harrassed mentally to get more dowry or buy a house with my money both by my in laws and husband.My father is no more and I have a dependent mother and sister to be taken care of.They harrassed me saying there is no support from my parents side and anu decision would impact my sister in future.i have come to my mom's place as it was my dad death anniversary. Now my husband is ordering me to stay at my mother's house and not to return to in laws place. He is staying with his parents in own house and they are rich enough. He is maintaining a high profile like has a IT job ,costly sports bike and a car but refuses to feed me and my daughter. I have health ailments like diabetes,bp and thyroid and had complications right from beginning of pregnancy. I had to bear all the expenses pregnancy and post pregnancy. I was not being supported emotionally,mentally, physically,socially. My in-laws always mentor him and manipulate him along with my sister in law. They know my health condition but still harrass me cruelly with words so I have had suicidal tendencies too. How Can I file domestic violence in case of this, as they abuse me and my daughter mentally,verbally, psychologically.Now my husband is blackmailing me stating if I goto in laws house he is going to escape from there and not let me know where he stays. How do I claim maintenance from him to myself and my daughter.I do not have means to support me and my family as I have severe health problems. I don't want to divorce him but don't have will to stay with him and in laws as they would influence,provocate him to torture and harrass me.I don't want to stay with him outside as he would harrass me daily verbally , psychologically torturing me. Instead of being support to a sick wife, he inturn tortures me with his attitude. If he moves out of his parents house and I don't know his address how would court order me to get maintenance. I do not want a divorce as he would remarry the second day after divorce but I want maintenance for my kid and me that covers her education,her expenses, my medication, medical bills,expenses,rent and I would like to maintain a decent lifestyle if not as luxurious as his.To prove my points I have few call recordings and screenshot of whatsapp chat that clearly asked to abort my child and abuse,bullying I faced.And medical records,bank statements as I paid hospital bills,and dowry too online,all expenses for my wedding online.
