Regarding domestic violence, maintenance and e pe from sects 376 and 420

I and my husband was in a relationship from an year. Suddenly we got to know that I am pregnant. First we think to abort but later I realised it is not a good decision. I asked him to marry. Firstly he was ready, both of families got involved and marriage date got fixed. Later he and his family denied. I was about to file a petition under Section 376 and 420 but they came for marriage. Marriage solemnised but they didn’t take me to matrimonial home. Whenever my mother asked to take me with him there, my husband denied. I, myself went there after 4 days of marriage. They were not happy and started fighting with me and abused me badly. From that day, I faced many kinds of physical and mental harassment. After 2 months I was compelled to leave matrimonial home with my all baggage. Now, I am 8 months pregnant and my husband and his family never call me, no care, no concerns, no financial help is given by them. Besides of this, my father in law called my father no abused badly. Also, my husband called and demanded mutual divorce.
