It depends on your wife and her side.
Second it is not necessary that a wife should be in natal home to file DV and or Divorce and or S. 125 CrPC and or even RCR. Lots of factors are considered / evaluated by a party in conultation with their circle of advisers before filing a case on one other.
Sum total she can very well file and may not even file.
You have to gear up or come to your social senses and or ignore and lead normal marital life whatever best suits your relationship with her and her side is best self answer.
Being in IT field does not mean a spouse cannot do DV! Coming late from work and or odd working hours itslef are violence to a wife who wants company of her husband. Infact there are more cases on IT spouse using S. 498a / DV than any other professions from metros.
BTW when no case even filed how you can have proofs against your FIL !
