Mental and financial harassment by wife

I have got married six months before and from the day marriage, I am being harassed by my wife with various financial expectations, by asking costly gifts and jewels every month and asking for foreign trips and for financial help to her family. I was doing all these to an extent of my financial condition. She is also working and earning around 50k per month. But she says she cant trust me and she wants save her money for herself. On the other hand, she demands money from me and not allowing me to spend anything for my parents and sister. She claims all the money I am earning is her right and I must obey to all her demands. She keeps blackmailing me saying if I don’t do as she expects, she will file a false complaint and she keep threatening me every time along with her family. She doesn’t allow me to work, sleep or even eat properly. Every day she fights and spoil my mental peace, if I say anything, she blackmails me saying she will put me and my parents in jail. Please advise, thanks.
