Mother in-law interference and guiding wrongly to my wife

Mother in-law in phone conversations to her daughter 1. i will find another guy and get daughter remarried. 2. just threaten husband once in a while. 3. do some drama saying she has headache, bodypain, etc. 4. Everyday speak of someone's divorce case, xyz family problems. 5. How law favors women and we can put someone in trouble. 6. She threatens saying, i give her mental torture just like that for no reason. 7. Always blames my parents, specially my mom. 8. she blames me saying, my parents have told her not to speak to her parents and not to meet them. She assumes everything on her own. Got married in Nov-2019 and she is working(40k is salary). we stayed together with my parents for first 4 months and later we moved to a rented house. (She pays current bill and for groceries from online and i pay house rent) Every general talk, she converts into negative and now i am feared to speak to her. Most of the time i have to act as if i have lot of office work Pls help me what to do next?
