Well, I see that Arpita and Yash had an amazing married life where Arpita was dominating Yash and she took the major decisions in life without consulting Yash. But Yashu being the jhoru ka ghulam,Didn't care about it at all. This is where the major difference comes b/w Yashita and Aarya.
While Arpu took single decisions and let Yash go wherever he wants like she let him go to work on Palak's b'day, Aarti is someone who believes in joint decisions and understanding of the better half. this became clear when Aarti stopped Yash from goin to work.
Yash will be quick enough to guess this difference I hope;-)
