Jagiya's feelings for Anandi changed in the first 6 months of his going to Mumbai. He disowned her when she went to Mumbai. She even met Gauri there and saw for herself how close Jagya and Gauri were and there was an understanding that Gauri would play the hostess in his party. In her confrontation with Jagiya - he actually said that their marriage was a mistake and he considers her a gawar and she should move on. Anandi knew about his feelings but kept it hidden from her family.
Then when he came home in the hols of the first year, he was exposed in front of the family, that he does not consider Anandi his wife and that he like the lifestyle of Mumbai.
Is it his fault that for 5 years, his family refuses to accept what he is telling them and continue to live in dreamland? Is it his fault that after he tells his family that he considers Anandi gawar, for 5 years they keep her uneducated? He has been steadfast on his stand from the beginning. It is only when the family came out of their fool's paradise that they started thinking of how to tackle the situation. But 5 years is along time to let things slip from bad to worse.
If anyone is at fault it is Bhairon and Anandi who refused to see the truth until their noses were rubbed into it. These two think themselves super-smart and know-it-alls, but it is they who are in a large way responsible for the mess they are in today.
Jagya might be a weak character and he might have betrayed every relationship, but he has been true to Gauri even at the cost of losing his family, wealth and social position. Anandi has the backing of the family, the position of the DIL of the first family of Jaitsar and ample financial backing. If Anandi has lost a husband, Jagya has lost everything in gaining Gauri.
Yet this is not to say that I support Jagya and Gauri at all. I think they are both wrong and hoping to build their own happiness at the cost of someone else is not going to lead them anywhere. But Jagya is not as black as he is painted to be.
Gauri till this day was a victim of deception, but today after knowing the entire story, when she decided to go-ahead with this marriage, she is architect of her own future misery.
