How can I change my thoughts?

My mother in law is very bias in  her approach. Why I say bias is because whatever I do, she never appreciates and try to give some negative comment. If the same thing is being done by her daughter, she will be all wow and full of appreciation. Many a times I feel she has a high sense of insecurity regarding her son that is my husband. I have no interest in coming between them because I understand every role has its own duties. My husband is also a son .

After I joined scholars this month, I tried analysing myself. I know I don’t feel like talking to her at all . It’s all because of the many circumstances which has been processed in my thoughts and that thoughts into feelings and actions. I know my husband must be feeling sad because I don’t talk to her mom at all. How can I handle this situation? Please help. Thanks!
