Contested divorce - respondent did not appear long time

Focus on what can be done and do not distract your attention on such things that are not material to the suit like diaries of your wife etc.  Let your advocate take the lead and file IA or take steps in expediting the proceedings.  In case of most of the wives, they are financially and physically dependant on some one, and if some one is not interesed in divorce there may be delay.  Your advocate can only guide how to expedite.

Yes it is possible for you to get Divorce even if she does not appear. File an Application for proceeding ex-parte without the Written Statement. If your wife has not registered her presence, carry some proof to satisfy the Court that the address where you attempted to serve her is the address where she is presently residing.
