What should i do?

Hi, Me & my wife got married in January 2015. Since then everything was fine but she was kinda over possessive. She always check my phone and ask me whom i am talking or chatting and we quarrel many a times on this. After a year she got pregnant, i was a school teacher and my principal fired me from the school due to the fact i was asking my PF, i was in really bad condition and nothing was going good, my wife started taunting me for the earnings and all. My co worker who was very supportive and friendly suggested me to work somewhere else, on the same day me and my wife had a fight and in the anger i left my home and went to delhi and started working with the co worker who suggested me to go there. I was called by police as my family started searching me, i came back after some days my wife left my home and went to her home stating that i had an affair with other woman when she was just my co worker, we went to her home and talked with her parents, they started shouting on me and my parents and refused to send her daughter to my home. So we came back from that day she never came back and she even gave birth to daughter but never informed anyone of us. Before some days she and her parents came to our home and said that she doesn't want to live with me and took all his cloths and belonging with her. and now after a month the sent notice that she wants interim maintenance for her and our daughter. She false stated that i had an institution and earning 50000 per month when i am in bpo earning only 12000 a month. Please help what should i do next??
