Hello,
1) You should file a case under Protection of women against Domestic Violence Act. 2005. You can also move an interim petition seeking maintenance and residence order , protection and compensation for the sufferings you were subjected to.
2) Instead of going to the WC you should have filed a petition under DV provisions or a maintenance petition under section 125 of Cr.P.C
3) It will take a couple of months before you get any maintenance. You don't necessarily need to remain unemployed to be eligible to claim maintenance.
