I was wondering about his.
Ishwari has always been so possessive about Dev...which is why she always avoided any topic related to his marriage.
The only reason she didnt object to Natasha's proposal was because of this business deal and how much it means to Dev. She has seen him talking about it with lots of eagerness and excitement...he really wanted the deal to go through...which is why she gave him space to think about the proposal on his own.
We saw how she convinced herself with a lot of difficulty to look past her insecurities and let Dev make his own decisions.
If the business deal wasn't linked to the proposal, she would have denied My Gujral herself and not left it to Dev.
But now, if what the articles say is true, Dev will be calling off the engagement.. ...that means he knows very well that the deal will suffer because of this.
It will make Ishwari wonder just how much Sona means to Dev for him to give her more priority over his business which he has painstakingly set up with such hard work.
This will make her even more insecure. Add to that Radharani's brainwashing.
I think this might be the reason.
