False 498a allegation

Hi, I was married in on 20th October 2014 and on 23rd October my wife started feeling pain on her lower back. When I asked she told that she had fallen before marriage and this pain happens sometime..but the pain did not stop. She had brought some medicines with her which she used and the pain was relived. But again on 2nd November 2014 the pain started then on 3rd November 2014 we took her to the doctor where he prescribed some medicines to her but the pain was not stopping so we took her to another doctor where MRI was done and doctor said her lower back bone was erosing and the treatement continued for 2 months but she was having pain so we again changed the doctor and we discovered that she had bone and lung Tuberculosis. We did everything to get her cured and we did expense of around 8 lakhs for 2 years treatement through health insurance and we have all the records and now she is ok but the medicines are still going and she went to her maternal house by saying that when she will be ok she will return back to home. But one day we got call from Mahila Thana that my wife has put a complaint that we are not taking her back.So we went to one of her relatives house and asked people to send her to our house and she also got agreed and she came with us to her matrimonial house, after few days she got a call from some one that I have married to another women and after hearing this she started quarelling to my parents and fighting with me over the phone. Since I was leaving in another town I tried to make her understand that this is not the case but she did not understand and went back to her home. Again after few days we got a call from Mahila Thana that she has put a application that we are demanding all the medical expenses which was incurred in her treatement and my parent and sisters tortured her and other false allegations. We went to Mahila Thana in two dates and now she is saying that she will not live with my parents and she wants to live with me in the city where I am employed. I am the only son to my parents and all my sisters are married.My parents age is around 80 years and they do not want to live the ancestral home and they want my wife to live with them.Even I tried to persuade her for the same but she did not get agree and she is saying either I leave the job and live with her or else I will have to keep her with me. Now the problem is I earn 18000 and living in metro city with family on rented house is very costly affair and there should be someone who should be there with my parents to take care of them. Being only the source of income I am very much depressed with her demands. She has ruined our reputation by alleging the false allegations against me and my wife. My question are:- 1) Is there any law where wife can claim to live with her husband where he is doing the job ? What if husband refuses to keep her with himself and asks her to live at his ancestral place ? 2) How can we fight the false allegations put against us ? 3) She is saying either to leave my job and come back or to take her with me to Mumbai, if I return back to my ancestral place I will hardly get any job and it would be very difficult for us to manage our bread and butter so please advice what to do in this case ? Thanks!
