Alimony & part of paternal property as wife & daughter living seperate

I am Hindu Male married in 2002. I have a 12 year old daughter living with her mom. My wife is working in Haridwar , living with her parents. I used to visit to her on weekends. But from last one year we have not met & she is not allowing for me to even talk t my daughter on phone as she claim I had physical relationship with one f the ex staff who is no more working with me & one of my school time friend has told her & she has phone recording as proof. Yesterday my parents went to her home but she refused and said she wont go for a divorce & nor live with me. I am 42 years old living with my parents. I am getting approx 50k monthly & she is getting approx 38 k monthly.If i will file a case she said she will ask for alimony , a part of parental property. 1. What should i do & 2. Can she ask for Alimony & Property & what will be Alimony.
