Custody of my daughter

Hello Sir! I am currently living in Singapore with my husband and 4 year old daughter. I used to work until last year but now I am jobless due to changes in the dependent visa laws. I have a lot of issues with my husband but I have been staying here Only for the sake of my daughter. I want to move back to india but my husband doesn’t want me to take my daughter with me. He is overly possessive about her and takes most of her decisions without my consent. I want to know if it’s possible for me to travel alone to india and file the custody of my child while my daughter stays here in Singapore? What are the chances of me getting her custody if I don’t have a job yet? Also, my husband cannot manage my daughter all by himself. He cannot cook or take care of the house and is very much addicted to his phone and his job. He has also kept a maid here because he knows if I leave he will need someone to help him. But The maid only follows my Instructions and I don’t want to leave my daughter in a maid’s hands.
