If as per the spoilers Diya married Ratan, they both are in some ways have similar fate. Both of them are proud, sharp, intelligent women married to immature men who are impulsive.
It is to note even Chote Thakur seem to love his wife a lot and is very affectionate but it cannot change the fact that she is always in that exasperated mood with his antics.
And even though Chote thakur seems to be cruel or bad, it can be easily attributed to his financial status.
(I believe Nancy mentioned in one post that somewhere in PPK it was mentioned that he squandered whatever limited fortune he had and had to be dependent on Ratan's father. But considering how Ratan is behaving most of the time, he will take the business down very soon. )
