Domestic violence

Hi.. its been 3 years of our marriage. At the time of our marriage my husband was not working anywhere but we married its love marriage. Beforre marriage he has given to much stress to me n my family. So my family said after marriage are not going to involve. I said yes . And after marriage it was going good also. But after 6 months he has beated me by his belt. And called my parents and he was saying if you are not here within 10 min I am gonna kill her . Going to make small pieces etc etc. He has called many times. My mother was countinuously saying its ok you come with her . Tomorrow is a Dashara.. he was not stopped. Then my father mother came there.. n my father beated him. N till now my husband is continuously daily also sending dirty messages to my parents and calling them and he is calling them a very dirty language . But they are saying you are there with him n if he is ok with you then we can manage.so i am tired because of this. So what i have to do? He is behaving sometimes good n sometimes too rude.
