I am so sorry about what you are facing. I would suggest you to file for child custody. Look for a lawyer who handles custody issues. My friend got the custody of her children after she hired a well known lawyer. I am aware about many lawyers like Bechara Tarabay that I found at http://fr.linkedin.com/in/bechara-tarabay-550b7929 . I am sure that an experienced lawyer will help you in the best way.
