Had sex then Call off the marriage after engagement

I got engaged in april 7th and marriage is fixed on march 16. It is a pure arranged marriage we met through the matrimony.After the engagement he is not ready to making phone calls for understanding each other.He is always invite me for visit his job location which is Bangalore. Because he was convinced me that he is not able to getting leaves. I trusted him so much.He prefer face to face communication only. I went Bangalore for meet him because of his pressure.He convinced my parents that i am stay his cousin home they are living with family. He always forced me to stay his apartment and forced for physical relationship.If i am not willing for that then he make a fight and threatened that he will call off the marriage and i am not a understandable partner.A unexpected moment we had sex without my permission and after that i am giving him my consent because of he treated me he call off the marriage.I can’t imagine marriage cancellation after the physical relationship.because of that i always accept every problems is because of my mistakes and he is not forcing me for anything.He is recording all these and he called off the marriage now.He saying i am always making problems and they are not ready for this marriage they need peace.He says he buys a car for me but actually he buy a car for him and i don’t know how to drive a car.After this he ask car EMI to me and he demanding 3lacks money .I give the money and he returned back the money just before call off the marriage. I lost everything now and i book wedding auditorium,marriage booked at temple , purchased gold invite some relatives.Now he saying i always threatened him for the marriage and he was not love me,only did the sex with my consent. He says he never invite me for meet him , i went there my own interest he is not interested that. I don’t have any evidence to prove because he exchange my phone and give a new phone without my permission just before he call off the marriage . The first time i had sex with him because of his parents.They invited me to their home town which is 5hrs far from my home for meet his sister she is admitted in the hospital for delivery .I am note ready to go there alone but his mom demanding me come alone if i am not meet his sister they suggested to stay in the hospital room.I can’t meet his sister then they are not ready allow me to stay the hospital room they book a hotel room and leave with my fiance.
