@Serbjit: Did you register your marriage before the actual wedding ?
If you both parties doesn't agree on the court order then I guess one can also nullify the marriage in cases like this.. i'm not very sure though
Otherwise take some more time to understand her better.
In my case I've postponed the marriage by few months to know each other better, but registering will go down as blunder of my life time.
I'm not this hopeless usually..big judgemental error
