And it was closed due to financial reason and lack of time, my father supports us financially and morally, after some time I started a Common service center which is on loan, after 1 year my wife also diagnosed With MDR TB, about 6 months she is with us after stopping her injection by doctor of govt hospital she went to her parents home in bhopal for few days, (14 sep 2017) and till date she is not get back to our home whenever I ask her to get back she always said that she is come after completing her treatment which was transferred to bhopal with out my knowledge, after few conversation she and her parents blocked my number and never talk to me nor provide any information about my child, even I make a complaint in women cell the come their and make a request that she is ill and start counciling after march, when the councillor asked her for get back to me she refused and said she will come after 1 year. The councilor said to me to wait for 3-4 months then they will start counciling. She make allegations that I am not working do not take care of her , do not get medicine from hospital for her , ya some time due to some work in my shop I am unable to go hospital with her but my parents or my younger sister or my cousin brother always go with her. My in laws and my wife always pressurize me to not involve in with my father business (my father have his own business) in which I involved and support him since july 2017 and now fully taking care of it.
