Bad relationship with husband

My husband does not talk to me properly since 2 years of marriage. Forget about physical relationship, He avoids sex and has never given me an orgasm. he does not even want to have an emotional relationship. We also have a son. My husband does not even perform his duties as a father properly. He is also in debt. My mother-in-law always fights with me. My sister-in-law is jealous of my beauty and wears my saree and salwar kurti without my permission, which makes me feel bad. What should I do?
