Case of dowry and domestic violence

Please can you clear one doubt regarding dowry harassment. I was married in 2004. My MIL took away all my jewelry. My husband wanted my father to give him his business. In 2007 my SIL `s marriage was fixed up. My MIL and SIL demanded a Honda city car for her marriage. I resisted the same. My SIL came back from her matrimonial home on 3 rd day of marriage and lodged dowry harassment against her husband for demanding an Honda City. I was blamed for breaking up her marriage as my parents had not gifted her a honda city car. She told her parents to stop giving me food from the only kitchen in home. I was left with 2 kids and no food. I shifted to my parents. In 2008, after counselling by police, my husband took a separate house. On first day , he left me at my parents promising to pick me and kids up at night. However when he did not turn up, I called him up. His sister picked the phone and told me to deposit copensation for breaking her marriage into her account , or she will break my marriage . Same night I was thrown out by my husband. is this not dowry harassment. Any judgements will be helpful.
