Harassment from Inlawas

Hi, I am being harassed by my in-laws. We are Christian's and we do 50/ 50 expenses in our wedding. In my wedding my in-laws did not take any expenses on them. My mom is a single parent and she has alone paid all the bills of the expenses. When asked about the money from my in-laws they say we are not responsible but it was decided before the wedding that the expenses would be 50/50. I got married to my husband in Oct 2014. After I got a job my in laws used to take almost whole salary of mine and whole salary of my husband as well. We used to be left with no money. They just bought a refrigerator in the house for us. Everything was done by my mother. Now we don't stay together but they torcher us. They harass me by saying my mom and me are "Faltu". They don't is good words for my mother. My mom is working in central railways. They forced me to abort 2 times and they said who will take expenses when I go on leave. They even say that they got their son married to me because of the property we have in pune. Kindly suggest what steps can be taken on this.
