Rokes, duties and responsibilities in marriage

I've been married for the past two years and have had a courtship period of two years with my husband. Both of us love each other a lot. Anytime we fight, its always about me not contributing anything in the marriage apart from love (which I feel but it doesn't reflect in my actions). And that I'm selfish. I don't cook nor clean the house (maid does it, in India its common), but I've always been there with him through his episodes of depression and when his family needed me. I try to make him smile whenever I'm around him. It hurts a lot when we fight over this, because this topic resurfaces every 4-5 months and is usually very ugly. He asks me to think what I need to do as a wife and I'm being truthful here, I'm clueless. I love him so much and it hurts even more. I want to rectify the situation, let me know the roles, duties and responsibilities of a wife. (He really loves me a lot too)
