Why did you even go back and go ahead with the arranged marriage in the first place?
Dude, have a spine. You're an adult capable of making your own decisions, but decided to do something you didn't want because "parents said so".
If that's the case and you can't think for yourself I'm having a hard time understanding how you're going to suddenly do something independent right now.
Might have screwed up the wife's life since divorce isn't looked upon kindly in India and she'll be marked as "broken goods", thanks to this spineless specimen. Also, was dowry part of the exchange?
If you want to make amends you have to sort things out and make sure she doesn't have to deal with your mistake.
