Dowry and mental harrasement by in laws.

I was married in 29th jan 2015. Since the beginning of the relationship my in laws directly n indirectly demanded for cash. After my marriage i was been mentally tortured for less dowry. My mother in law used to torture me by not providing me the basic nessecities like food water etc. I anyhow managed to leave that place n shifted soon with my husband. My husband was unaware of the torture done with me moreover i didnt had the courage to complain. My husband was also involved with another women after our marriage when i cought him red handed he appolozised and promised not to repeat again..it took me quite some time to forgive him so i told my in laws about the incident. Since den my in laws have more tortured me verbally..my sister in law n her husband have abused me verbally...even my mother in law has said bad things about my character among the relatives. Now she says to end all relationship with me...i had given her a legal notice to return back all the cash and gold silver things given in the marriage by my parents. Instead of returning my in laws are challenging me to see in court. Kindly suggest what should i do...
