Wife Doesn't Want To Live Together

Sir/Mam, I am a 28 years old male, born and brought up in Kolkata, Marwari by caste married to a Bengali girl around 4 years back. Within one year of our marriage we got blessed with a baby boy. In my family there are total 4 members, my mother, my wife, my son and me. My wife who is a MBA - HR was earlier working in a private limited company earning around 25k per month has left her job recently as she has decided to do work on freelancing basis from the next month/new year. I am earning 50k right now from my job, able to meet livelihood expenses and pay my EMI for home loan (taken jointly in name of me and my wife). Apart from this I have a bunch of debts including personal loan and credit cards taken jointly and some are in my individual name of me and my wife which was taken for making down payment for our flat (home) and a business in which I got huge losses and had to shut the same, EMI of which I am yet struggling to re-pay. I have recently got to know that my wife had been cheating with me having relation with my cousin brother. I have few pictures (one where my wife is hugging him) and few audio recordings of their conversation in which she says that she never loved me and married to me even after her family did not want to because at that time her ex left her and she had no hope while the surprising fact to me is that I always thought that we had a love marriage in which parents agreed for us to get married to each other. She was never happy with our marriage but since it was a social marriage and we also have a baby, she is still living with me. Now my query is as follows: 1. I have got a job recently at a place (town) 250kms away from my house in Kolkata and now want to bring my family altogether here for which my wife says that she does not want to come to my job location stating reason that Kolkata is a city and my job location is in a town. She does not mind me bringing my mom to my job location but claim a full time maid along with rent expenses to be borne by me where she will be living with our son in Kolkata only. Are her demands reasonable and if not what can be done? 2. The flat for which we took home loan has been completed and is due for registry. Now I am worried that since she had done only 20% contribution rest 80% contribution will be done by me I do not want her rights in this property but since the loan is in joint name (me and my wife) is there any way out that I can get her rights out of this property? If yes then how? 3. Since I already have a bunch of debts, and considering my wife educational qualification and her ability to earn, do I really will be asked to pay maintenance and if yes then how much? 4. She also denies being physical with me. It had been more than 6 months that we have been into each other. Even she does not like me small touch from me now. 5. Now considering all these scenarios, I really think that we cannot reconcile ever and its better we get separate only. Need your advise.
