Wife Torture

Ours is a love marriage. We got married 9 months back and we still have not consummated. She had got a job abroad and within a month of marriage she went to Singapore from her parents house. During this one month before she went to Singapore, she stayed only for 3 days in my house. Their family is financially strong and they wanted us to stay separately or even to stay at my wife's house. While going to Singapore she called my mom and threatened to file a case against my mom, sister and me as I did not agree. I have old aged parents and an unmarried sister to look after. She's earning more. Now after 9 months she has come back and filed a NCR at Shivajinagar women's police station that I'm not allowing her to stay in my home and we are demanding dowry from her. I went to the police station and they also threatened me and took a statement from me that I'm ok to stay with her if her parents come and leave her in my home. She has given a counter statement that my family have not allowed her to stay from last 9 months and on what basis shall I come and stay now. But the fact is she was not in India and was working in Singapore since a month after the marriage. She has threatened me to file a dowry case against me. I have below concerns: 1.Can I get my marriage annulled or get divorce since we are not staying together for the past 9 months. We have also not consummated which i believe is a cruelty towards me. 2.Another fact is she is earning more than me, will I still be required to pay her any maintenance or settlement money to her. 3.I do not want to pay any money since I earn less than her and given the fact there's no fault of mine here and I have my old parents and sister to take care of. 4.We have never asked for any money from her or her family as it was a love marriage. She is filing a false dowry case against me. Will I be able to prove it false based on all the above facts and git rid of her. We have registered our marriage under Hindu marriage act of 1955. She has caused too much of trouble, embarrassment and harassment to me and my family and I don't want her back in my life and I can't afford to give her any money. Please help me. I'm in a very very bad situation.
