Cruelty by wife and in laws

I have been married for 1 year now, I have 3 months daughter here is my story. My is a arrange marriage, before marriage I had mentioned that I will mot leave my parents, after marriage my wife forced me and my father agreed and so I left my house and living in rented house despite in same city. Secondly when I got separated from parents I shared to my wife you also need to help me in the household expenses as I have home loan one me. She agreed until we shifted to new house and as soon as we shifted she changed her words, I shared this to my I laws but no change rather they told me that I need to do all expenses and pressure me every now and then; Now after I'm separated with my parents my in laws kept coming in my new home everyday with some or other reason and yes the house is near their residence and kept putting pressure on me to do as my wife says bcz what understood so far they want me to become her dog. Now when she was pregnant as per Indian tradition the Expenses of qst delivery should be done by in laws but my wife did the most expensive dr and made me paid the fees, I payed considering that it's my child no big deal but always knew cunning nes of in laws. Till delivery she tortured me lot for every small small things infact she gave me dhmki like she live do adultery and many men are behind her. Eventually she shifted to her parents house when she was 5 or 6 month pregnant but I kept taking up the expenses of Dr. I also have her chats where she had specifically mentioned that she is ready to take my child and live alone without me, there many such instances whenever I go home I.e my parents house she finds a reason to create fight. After delivery been almost 3 months she and baby r still at my in laws place we are having bit tension between us. My in laws just try to find any flaws in me and pressure even so that they had given dhamki of filling cases against me. Pls note I don't drink nor smoke nor don't have any bad habits or any litter around frndz. Now every now and then my In laws change their word and my wife if any simple goes against her will she find a way to make me pay. Also note my is pure arrange marriage and there is no dowry taken but every now and then my wife posts things on social media as if she is going through lot of pain and demean my family, my in laws also do the same. In such situations what should I do.
