My elder sister is having multiple gallstones in her gallbladder. Doctor said to undergo a surgery as soon as possible. But my brother in law has been completely ignoring her illness since very beginning. And I want to tell that domestic violence in her house is very normal thing. He use to torture her both mentally and physically. Now my brother in law is telling her to vacate his house and go anywhere she want. Also he added that he doesn't want to bear her medical expenses (though he is earning a handsome amount of money every month from his medicine store). Now my question to all that what should I do? My elder sister's life is in great trouble.
