I love a girl who also loves me and wants to marry me.?? You only love her ?? Don't you want to marry her ??
A woman can seek the help of the police to help her stop her marriage if she is being forced to marry against her will. However, given the level of mistrust that prevails in our society vis-à-vis the police, such an intervention can boomerang on the woman and may lead to more trouble.
But yes the police can help to get you married because you are both Adults .However, in case of life threat for you or your girl, then you can go to the police station and explain them the situation.
In this case also, first police will call both parents and try to find an amicable solution. If that does not work and if you both are Major (in legal marital age), then police can help you get married under their witness. But again for that you will have to go check with the local Police station if they have a Police Pandit ? who is a Diary guy to all such Chowki Marriages .
,Later the Police diary guy send the Marriage recipt to Marriage Registrar and to get the same registered . Marriage registrar send the Marriage certificate copy to your address that is registered with Police station at the time of marriage !
