Torture by wife n inlaws

My wife and her parents, since 3 months of our marriage keeps on fighting, abusing my family and me. After every fight, she packs her bag and shift to her flat nearby to my home,, call her parents and stay there for 1-2 months and keep on torturing me through msg and calls n then return to home… she has done like this 4-5 times like this since our marriage of 2.5 years. We have a kid of 1.5 years…she doesnot allow me to tk the kid anywhere outside and if i take him outside for 5 min also.. she starts fighting and her parents keep abusing me on call…. Everytime i used to say her dont leave home like this..but she nvr honoured my request.. Even when my kid was only 2 months,,, she n her parents hv taken him to her hometown even after my denial.. she keeps on dis respecting my parents… My parents both are ill and get stressed by all these issues. She has again home to her own flat and asking me bring court permission if i want to see my child or else we wont allow me…. She also told me to leave my parents and i have to shift in her flat.. if i want to meet my child.. Pls suggest the way forward.
