Request for an appropriate advice.....

Hello Sir, I am Asha, came across this website and found helpful for people like me. I have a question regarding my cousin and her marriage. My cousin got married before 6 months without any knowledge of the groom's background history through a leading online matrimonial website. The groom has concealed every minute detail of his financial status, affairs and former job. Actually, he cheated my cousin's family with his false interpretations, he is not working till now(don't know the exact period of unemployment). He was involved in some fraud case in his office. At the time of wedding, he and his family was given many gifts, in the form of jewellery and cash by my cousin's family. For first two months he showed no sign of torture or abuse. Post marriage also, he has been seeking financial aid from my cousin's family. He is depending on his father for food and shelter by doing nothing and doesnot even care about my cousin. He even distanced my cousin mentally and PHYSICALLY. My cousin is treated in her in-laws house as a domestic maid only, she has been suffering severely with mental trauma due to her husband. He abuses her all the time and always keep on asking her to get money from her family. My cousin's family is bearing all her maintenance charges from the time of marriage till date. My cousin also got some anonymous calls and messages after marriage about her husband's affair. When her family confronted him about his affair and job, he keeps on making excuses without accepting his flaws. He is avoiding my cousin's family without meeting them. He is suffering with severe mood swings and my cousin is the main victim of his torment acts and sins. She has beared all the torture, in the hope of a better future and also to avoid divorce. Finally, after many attempts from her family, she has agreed to go for divorce. Therefore, I kindly request you to advice my cousin and relieve her from her miserable marriage trauma. Many Thanks, Asha.
