Devorce

I m a male. I married a girl before 2 years. But after living 2 month with me she went to her parental home and when after my several requests she came for 2 to 4 days and again she left. This was continuied for the last 2 years & in 2 years she lived with me maximum 4 month allover. Whenever i approached her to to come to me cuz i want to live with her she refused or if she came for 2 to 4 day she denied to work any home work or to cook food for me or anything. She told that she could not work cuz she does not like to work. I just requested her to cook food for me 2 times in a day but she refused & told me to say this to my mom or sister. Last year we was blassed with a baby boy. I though that if the baby will come our marraige may last but i was wrong. She even separated me from my child. She does not come here to me so that i could meed my child, she told that if i want to meet my baby i have to come to her parental home which is in different district. I can take the custody of the baby after divorce if she want. But if she will not give me my baby i m also not in possession to give her any maintenance. Now tell me sir what should i do if she is not willing to live with me. Even she is not ready for mutual divorce. She just wants me to suffer & a tag as married woman. I m a poor man, a tution teacher by profession. I earn maximum 6 to 7 thousand monthly. She is a non working woman. I have not that financial phase to give her or to the baby any maintainence. She went to her own willing so why should i be punished. I want to get rid of her without any maintainence. Plz suggest me what should i do?
