Not allowed to visit my child

Dear Sir, I got married two years back. Me and my wife had few disputes over her arrogance towards my family. When she was pregnant I asked her to deliver baby in my parents home as there would be someone who could take care of her and she rejected and denied going my parental home and then I asked her to deliver baby at her parental home due to safety and security. Due to some complexity delivery was abnormal and one month before the due date at her parental home and I was informed only after the successful operation. The child was in NICU for one and half month. Due to some issues, I visited her a week after delivery and she was in no mood to meet me that I understand. I knew these were tough times. Since I cannot visit her regularly due to my professional limitations and long journey, I wanted to visit in next month and informed her. She called me and stopped me visiting her and the child. After intervention of my friend , I visited and asked her to come with me. She denied stating the poor health of our son , I agreed. Since the charges were high for NICU they wanted to pay me upfront but their intentions were not right and I agreed to pay only after they give me medical bills and let her come with me. She denied to come and never let me take photos of my son. I returned back to my city. Tried to convince her but all went in vain. After five months I visited her again with my father after again they refused to come. Since I lives with my sisters, they wanted me stay alone with her. I had taken a separate rented flat so that she don't have any issue. Previously she had expressed handling my salary account and financials that I denied as that was not right time.I informed her but she is not returning from her parents home. Its one and half year, neither she shared any photos of my son nor she is in mood to return. Due to this I have gone through humiliation many times. Everyone in society ,in office asked photos of my son and inquires on well being of my son. I don't have any answers. My family is also going through humiliation due to this in society and in relatives. Now I want my child's custody with me.How can I proceed from here. Thanks Alakh.
