Domestic Issues - Violence, torture, abuse etc..

Dear Advisers, I am Lata aged 28, I married about 2 years ago with a man who is working with Indian railways. i lived in gaya with my in-laws and my husband posted in Mugalsarai. he use to visit us on weekend. Initially, Everything was going good but after just a month my husband and in-laws had changed drastically. They had started abusing me for no reasons. whatever i do i get scolding or abusing without any reason. I was completely shocked to see all this but i thought things will be okay as time passes but nothing happened like that. The situations were getting worse day by day but i was happy that i was blessed with a baby boy and i thoughts now things with go smooth. But scoldings,abusing turned into beatings and whenever my husband comes to home he use to beat me for any reasons. my in-laws makes several stories to make me hit by my husband. some times my in-laws also beaten me. After this harassment, i decide to go to my husband place so that i can able to make harmony but happened opposite of this. He use to beat everyday, sometimes 5-6 times in a days. Somehows i told to my parents and my parents tried really hard to solve this but nothings happened positive even i gets more abusing and beatings and also my husband abused my parents. My parents somehow took me to home and tried to solve this issue with ease but my husband and in laws stop responding. they stopped picking our numbers. I feel like abandon so decided to go back to my husband and i went alone to my husband place but no change i found. Some days back, he was beaten me like anything and i went to near by police station in mugalsarai, UP and lodged FIR against him, called my parents and went home in Bihar. Now, I am at my parents place and i dont know about legal processes. Kindly guilde me about what will be my next step or how to handle this kind of case. I don't want to go back to my husband but i want to secured my and my child's life. I am not educated enough to do good job and i have no money to fulfill my basic needs. plz guide
