Can wife file a false 498a & DVA after 6 months?

Hello, My parents in law took my wife for 2 days on the pretext of Bhaiya dooj last year. After 2 days, wife stopped taking calls/msgs. I called her eldest sister to ask what had happened. She said her sister isn't willing to come back as she says that I do not take her to her maternal home every 2 months, don't talk to her middle sister & her husband & all other flimsy excuses. Her middle sister, who herself got separated from get in-laws & staying in her maternal home with her husband & kids had a great influence on my wife & she tried to control even our personal decisions which affected our married life adversely. She was supported by her mother in all this. I resisted to their interference but they wouldn't change which resulted in altercation between me & my in laws & after few days they came & took her along with them on the pretext of celebrating bhaiya dooj which she also celebrates with her middle sister's kids as she didn't have a real brother. My wife was earning around 20K/month before marriage but left her job just before marriage & her parents are also seeking that compensation. Now she puts her pictures on facebook partying with her sisters & her das says that she is in depression!! Now it's been almost 5 months. In between I talked to my wife somehow over the call & intentionally asked if there was any harassment or dowry issue to which she said no (this was recorded). But she remained adamant that she doesn't trust me when I tried to convince her of more frequent visits to her maternal place in future, etc. Now, last month, their family met ours & asked for out of court settlement amount of Rs. 25 lakhs which our family has denied. Now it's been a month since that meeting..my dad called hers to know their decision to which they started speaking ill of our family & said we have ruined their daughter's life & same will happen with my youngest sister,etc. My father said that we are ready to give their​ items & jewellery back at any time & can only afford to pay the difference amount of the wedding(from girl's side) & sagan ceremony(from boy's side) to which her father said that they are not beggars & disconnected the call. Can they file a false 498 & DVA even after 6 months of estrangement? Can they seek divorce in the absence of any solid ground? What legal actions can I take if I also don't wish to continue this relationship? Or shall I do nothing & wait for them to start?
