it is not like they listen to women always. for Police whoever comes 1st they think they are right.
reporting is our duty,
if she file case after you file divorce, then you can say always that in revenge she filled 498a or dv and those old days are gone, now there is scrutiny and punishment if police file false criminal case on you, without evidence.
recently i told 2 of my friends, report all threats to police and followup with RTI, now both girl sides are talking about compromise, even police is not ready to listen/entertain girls much.
anyway, its upto you,
