Dual marriage case and fraud

I am in a relationship with a guy since 11 years. He took money from me and assured to marry me but then he married someone else. post that I approached the police where he agreed to repay my money back in 2 years. He came back to me saying he still loves me and he was forced to marry the other girl because of family pressure. He married me without divorcing the first wife with whom he had a child. He assured me to disclose our matter to both of our families after we have our baby. After a long struggle and doctors consultation we now have a 7 month old baby. Since past 4 months he is not in contact with me and his family says he is never going to come back and asking me to take care of my child alone. I had spend all my money for our marriage, medical expenses pre and post delivery. I dont have any money left with me since he have stolen jewellery from home and marriage album also before leaving,I have no family support since he detatched me from my family 11 years ago. when we initially met. Kindly suggest me the next step I should be taking in order to get justice.I dont want him to come back in my life. I want him to return my money back and compensate for all the losses I have incurred for these 11 years along with the child's maintenance. I am not in a position to work since I am left all alone to care for baby. Awaiting an advice on this matter.
