Husband not taking care of me and my child

My in laws used to say wrong even i do small things and they do not allow me to go for walk in evening and does not allow me to stand outside. They used to cook in home occasionally and does not allow me to cook and saying your cooking is not good most of the time order food from shop. After delivered a girl child i told them i cook for myself and started cooking for me but after that my father in stop buying vegetables so i used to take rice oats and upma as a food for one month. Due to this stone formation in gall bladder occurred and done surgery to remove the gall bladder. After that i came to my mother house with my child for rest. First 2 months husband used call and ask about the health and 2000 rs monthly to us. Afterwards he stopped calling and doesn't give money. My in laws having 4 portion in the house so i asked them to give me one portion so that i can cook for myself and take care of my health. Even my husband has separate house which built on his own salary. They are not accepting and my husband brothers are living in separate portion. They are not attending the call and they are telling me not to come. All my expenses and child expenses are taken care by my parents What should i do how to unite with my husband and money to take care of my child
