Making 1st move to divorce

Hello, It's been 6month I m married. My in-laws is harassing me everyday. My mother in law n sister in law picks up fights on small matters. I almost work like a maid. They don't give me any respect. They keep on talking on my look and my dressing style. I don't hv any freedom. But I went through all this situation because my husband was with me ???that I was thinking till last month. Last month I went to my parent house coz my dad was not well. He was completely on bed. During that time my sister-in-law delivery was their. I gave 1st preference to my sister-in-law delivery. After 15day I asked my husband I want to visit my dad but he was against of it. Then he agreed n send me. I went alone to visit my dad. He didn't brother to call my dad to know his health. I was their for 10 day. After 5th only my husband call n ask me to come. I told I have dad work I have to complete which he already know. But then he talking about divorce n all. I went back, he said in anger he said all that things. But now his behaviour is completely change. He also started talking in harsh way with me. Right now with my in-laws he also started speaking harshly. Last week, my mother in law n husband visit my dad and started complaining about me. And my mother in law said now his son my husband will never come at their home. They insulted my dad. On that day I didn't went with them because for me now at my in law, I don't have any one who will stand for me. Right now, I don't want to go back. I want to stay at my parent house. Please help me.
