Wife not coming back home after delivery of baby

I stay long with my mom and dad. After spending the last 5 years and 9 months of pre pregnancy at my house, my wife delivered a baby and she went to her parents house from the hospital. She is now saying that she would return only if I abandon my parents. My parents are old and I am very close to them and they need me during this period as they have no where else go. I can’t image myself moving out I wanted to spend time with my new born kid along with my family but my wife is not returning and kind of blackmailing. I am now feeling very sad and least bothered about my wife who seem to be playing a game but I would want my daughter back in my house. Please guide me on what all options I have here
