Male and mother in law harrasment

I am married working woman aged 28. .I used to give allmy earnings to my husband. I have twin babies. Under covid circumstances i have been doing Working from home since 2 years and still continuing. As i was carrying two babies i was suggested not to travel and to be under a gynecologist who knows my health condition. My delivery has happened at my husbands place and not at my mom's place. my mom has come to my place (Where onmy me and my husband lives) to help me at my maternity period. As I am having two kids my mom was staying along with me to help me in taking care of babies and household things. when kids are 4 months aged my mother and father in laws come to my place and starting harrasing me physically and mentally. when i asked for any help , my mother in law never helped me in kids or kitchen or household things instead she never wakes up from the bed saying she has leg pain. she wants her food at a correct time, otherwise she used to discuss all the useless things with his son and my husband used to torcher me. when i say i have back ache my husband used to say your mother is here to help you so if you have any problem go to your mother and do not discuss with me. then i understood that my husband and in law's does not want my mother to stay at my place and their intention is to send put my mother from there. one day my husband asked my mother to book a ticket and leave the house. after that my in laws went to their home. after all these i convinced my husband that it is very difficult to manage WFH and taking care of 2 kids so as long a WFH exists i wil go to my mom's place and work from there. he dropped at their parents place from there i took my 9 months aged kids along with me to mom's place. from that time till now he did not come to see us, he did not send even one rupee or a chocolate for his kids, instead his parents making calls to my mother side relatives to get divorce. kindly help me on this.
