please share complete facts and story , if you are in noida then might be i can help .
within one year of marriage , divorce is not allowed , better get her history and file for anulment.if you dont have her past history to make your case success then if you want divorce then forget your enjoyment in life for next 4-5 years and start preparing for CAW,Court,498a,406, DV and other acts which might you get soon,initially you will get pain but after that it will become part of life till final court order
non-relative pic might be her previous hubby/BF/Cousin/Friend/classmate etc , so its not a proof to contest.
go again to FIL house and get her and other members phone / Laptop and copy it completey and do a scan of it , Whatsapp/FB/Gmail can give you hint or clues.
You have not mentioned your age . income etc, while running to court this also matters.
if you want to close your relationship , throw money and buy MCD.( still it will take atleast 1-2 years )
so fun for 7 days in FIL house is going to cost 10-20lakhs or 4-5 years of tension or both.
