Harassment and cheating

I met him on dating app tinder. He told me his story of how he is unhappily married and hence he downloaded tinder to find some escape. I told him how my boyfriend cheated on me and I too downloaded tinder to escape. We started talking and I told him how in India, I managed to stay single for 36 years by finding compatibility in women as it provides satisfaction and it’s safe too. He loved the concept. We went out partying and on holidays. I am a spendthrift and I use to spend a lot. Sponsored all the holidays. He said he found strength from me and he wants to officially file for divorce as he has fallen in love with me. His wife asked for 55 lacs. He being a govt servant didn’t have the money so I gave him the money. He got divorced and the next day, left me for another richer tinder woman. He disappeared for 4 months after his divorce. Came back after months and said that he realises what wrongs he did. He made a promise to me to marry me and he will. I asked him for a promise that he has to leave this richer tinder woman and all his past behind then only ask me for marriage. He said yes. On our wedding day, he made a 40 minuets FaceTime video call to this rich tinder woman. I found out and was going to call off the wedding. He apologised and said, it was a closure call and that he loves me. We got married. Been 5 months. I have been beaten up 5 times in these 5 months. Every time so bad that I could not go to the police station. He strangled my neck till I passed out. Reached the icu once. Left ear drum is hurt. Fractured my ankle once. My mother is a heart patient and will be going for a bypass anytime hence I can’t tell anything to my parents. I’ve given some hints to my sister. Can’t tell her completely as she will ask me to leave this man immediately and file a complaint. All my friends are aware of my situation. His complains for me are that I have personality disorder. When in bed we talk about threesome and once I reach orgasm and I’m done then I become normal. I tell him that’s because these are fantasies to which he says no, he remains in those fantasies and I lie and cheated him by not making those fantasies come true. He is still in touch with this rich woman to which we continue to have fights and he is not willing to let go of her. He says I have anger issues. In my 36 years I have never raised my voice but in my 5 months of marriage I have thrown things. Why. I can explain. He is drunk and wants to talk to me. I say, I don’t want to talk so he throws water on my face while I’m sleeping in bed so I throw something I see on my side table. He is a smokers, sex addict and an alcoholic. I want to try my 100 percent before I take some drastic measures. What kind of proofs do I require so that I’m prepared, just in case I decide to give up on my 5 months marriage. I feel he married me only for the money and he has cheated me. Now he wants to mentally torture me.
