Legal advice

I got married to a divorcee in 2007. Got pregnant with our first baby & miscarried in the first trimester due to mental harassment by my mother in law and she made me carry heavy items during house shifting inspite of knowing that I was pregnant. The following year in 2008 I delivered our 2nd child battling a lot of complications during pregnancy. My mother in law didn't want to see the baby as she was baby girl and they wanted a grandson. I'm the oldest daughter in law of the house. She has always shown biasness between me n my sister in law (a Punjabi). I was constantly taunted as I didn't earn much like my sister in law. My babies were never taken care of even after I got a maid for them. All that my in laws had to do was keep an eyes on the children in the presence of the maid when I was at work. They refused n made me throw my job more than twice as I had no support from them. I lost my own parents in 1990 n 2003 to cancer and brain hemorrhage. With no one to care for my girls I had to take a break in my career. Inspite of what not my in laws had subjected me to I did n given them whatever they wanted as per my capacity. My husband too has always given my in laws money every month in cash and also taken care of their medical and hospital expenses as and when the need arose n still doing it. 2009 my brother in law n sister in law move to hongkong permanently. My brother in law never wanted to work under anyone hence wasn't working inspite of being a management graduate double post graduate. He's sitting at home investing in shares from hongkong and claims to have made chores of money. Only my sister in law works in hongkong n earns a very well paid job and they can afford 2 maids full time residing at their place. Just before covid began my husband lost his job n was jobless during covid for 2 years. We survived on whatever savings he had paying for children's school fees, tution, books etc. Every month was a hand to mouth situation. That's when I got a job of barely 30k a month as my gross. My mother in law started fighting with us to give her money. He didn’t have a job n she expected me to give a part of my salary to them. My brother n sister in law tpo fought with us to give his mother money. Please note they had a job n my brother in law had a lot of savings then too. Now he is arguing with us that he made his parents stay in his Mumbai house for free n he had pay for the light, gas etc expenses because his parents were there. He's threatening to file a case of abandonment on my husband n his elder brother whereas my husband had paid for my mother in laws hospital bills completely. My in laws have 7 lacs rupees in PO n also have their own 1bhk that is closed. Please help us. What should we do . They’re (brother in law n mother in law) are threatening us in ways if filing a case against my husband as he does not want to put in half of the expense for his parents. In laws are taking brother in law side. Please help
