I am blamed and cheated by my husband and his parents.he married me saying he was single.Later i came to know he was already married and had a son through the mail he sent me after he went to his work place.when i told him i will file a case against him he came back to me after few months to stop me from the case.while he was with me his family blamed me for his kidnap.now i am in problem because of him.as a proof i have his mails that he had sent.how can i get justice for his doing as he has played with my life and has used my body for his satisfaction fooling me with his false stories.
