Mother-in-law threatens to kick me out of husband's house

I got married in December 2016 in a bengali family. When I went to my in-laws house after wedding. due to poor health I was unable to assist my mother-in-law in household chores. This happened for sometime as I was suffering from fever. Then one day, she blasted all her frustration on me by cursing me, my parents and even asked my husband to get divorced from me. Before coming back to Delhi, she said sorry and I assumed that everything will be fine now. But I was shocked to see her reactions. Then in February, my husband went to Mumbai for some official work. He extended his stay and gav every less number of calls to me. He did not leave suffecient cash to me as well. My in-laws have influenced my husband completely. When ever we have any quarels, my husband shares everything with my mother-in-law. My father-in-law calls my parents and threatens them that I am unsuitable for a married life and I need to leave my husband's house. This creates tension for my parents as they are retired and suffering from heart related disease. Now-a-day, i get threat everytime we have a quarel that they will compel me to leave the house. Please tell me what to do... i am a working woman. my company has salary issues and my payments get delayed everytime... i am completely depended on him financially... he often denies financial support to me
