Shinya,
I agree with what Koolsadhu has replied to you.
I am yet to see any evidence of Ganga taking it easy because she thought "what's the point of studying? I am eventually going to be the haveli bahu anyway" . She never once thought that. And we cannot attribute that to her UNLESS THERE WAS AN INTERNAL MONOLOGUE SHE HAD WITH HERSELF WHERE CVS EXPLICITLY SHOWED THAT SHE HAD THE PLAN TO JETTISON HER STUDIES IN ORDER TO BECOME HAVELI BAHU.
I am yet to see any evidence that Ganga failed to reach any of her academic goals because she was lollygagging or daydreaming about daaktar-sa. If she had failed in her 10th std exams or failed to achieve a seat in the nursing college admission, yes, your case would have merit. But in the current situation - she both passed her 10th exam and got her nursing college admission.
There will always be time-lags between exams and results and stuff. Even now, it is not that she is deliberately withholding going to the nursing college in Mangalore because of her love for haveli folks or daaktar-sa. The course hasn't started yet, and may not for another one or two months.
If, after receiving admission, she secretly wrote to the college to cancel her admission, because she wanted to continue staying in Jayetsar, then fine, I would agree with you.
There has not been any delay by Ganga in passing exams. It has not been that she has failed her 10th exam three times, and it has taken her another four years to pass her nursing exams, and that she has been deliberately delaying passing her exams to stay on in the haveli.
To say that "she should have got a job, any job" is also a little ridiculous in the context of Jayetsar. It is not like that conservative society is abounding with any jobs for 10th pass women. If at all a woman is to have a DECENT job, she will need to have training of some sort. She took whatever job the Singhs/Jagya gave her in the hospital. That job too was based on the good will of the singhs and not her academic qualifications.
As far as the falling in love part - we cant help whom we fall in love with. You are saying "why bother falling in love when it is a dead-end to begin with" -- but I don't think Ganga was falling in love with the intention of an end-goal -- to become his wife. She just fell in love period. We cant control our feelings for people. But she has never acted upon it.
If she had gone straight to Jagya and said to him "Please don't marry saanchi, marry me instead, I have feelings for you ", or tried to break the rishta, then it would be one thing. But she never acted upon it.
