Can husband avoid wife's calls and texts legally and not give her pocket money?

Hi after my father's death I have to look after my mom and stay with her for 8 months. I have informed this to my husband earlier. Still he is playing tricks with me so that I either leave my mom or leave him. At this point since I am a housewife I cannot leave him but now he started avoiding my calls. He stopped sending me money and said if you want food stay with me. I went to stay with him along with my mom but he quarrel for petty reasons like the food I cooked is not tasty, etc. Even when I used to stay with him he don't give me money for my needs like buying news clothes for festivals or for decoration of house during festivals. I came back to my mother's place because of some bank work and was planning to return on Jan but now he is avoiding calls. Please guide me that can he avoid my calls and also guide me can I ask him for a small amount of pocket money every month?
