Dowry harassment

Got married with 125 sovereign gold and my father in law took 5 lakhs cheque from my parents before marriage. My mother in law beated me after 3 months while I was pregnant. Then they start using bad words and always creat problems. After delivery my husband took me back to his house and beated me and bring me to my parents house and he left. Few months after husband and his dad came to my house and ask for more dowry. But we refused to give. Then they send a lawyer notice putting all blames on me, saying that I never respect his parents and I am not a dutiful wife etc. Before I reply to this letter, he convinced me to go with him. So I went with him to a seperate house. I got pregnant again in one month, he started to beat me again and put a complaint on me in the nearest police station. Police didn't told me what was the complaint, but asked me what happen, I told them everything happened. So they asked me do you want to stay with him, I said I am not safe, he is beating me. So they ask me to write it and let me go. Now I am in my parents house. I have Facebook message which he send saying where is gold and money? The child is not his? You are like a dog who got beating from my mum and sister? 1. What way I can proceed? 2.is it go against me since I didn't reply to first lawyer notice which he send it to me? 3.is that evidence is sufficient for dowry harassment and domestic violence? 4. I am two month pregnant , can I abort it now ? Does it have any legal consequences ?
