mental harrasement from spouse family taken my kids

i've been married for 4 years and i have been bleesed with 2 children one kids in 2 years 6 months and my second son is 1 year 7 months ... from the time of marriage i have been abused , tortured , slippered by my spouse and family due to my caste it was an arrange marriage . even for having sex i was literally abused by words by all means . Even my parents are facing the same situation with her and their family . We have run thru almost all the cops in our area At the time when my 2nd son was 4 months she gave my second son through the cops in written stating that she does not need him and wants me to raise him , I raised my second son until he was 1 year 2 months again thru cops she threatened me if i did not rejoin with her she will take away my second son as well so i had no other choice other than to rejoin the cops adviced her not to treat me or my family ill but after 2 weeks situation became worse and started with abuse once again so we ran into a fight now she took my sons
