What's stopping the two? (Saraswatichandra)

It's very difficult for me to accept an ending that looks absolutely redundant. I end up feeling why couldn't the director be more brave and experimentative. Why couldn't he marry off a widow to her true sweetheart? Why does he have to depict her accepting her sad fate and the decisions of a taboo-ridden society? And, why on earth does he have to make the lead character procrastinate so much???
