Looking at the way the show is proceeding!!
I am not trying to justify Dev !!
I know Dev had made so many promises.
He had broken them all .
I must say - if u think about Sona's promises- she told she will support dev's decisions . If Dev leaves her also, she won't leave him .
Why she promised like that - probably in the back of her mind she would have known this will happen because of iswari.
Coming to break up part - they were together for 1-1/2 months;
Yet their bond is shown to be deep
Dev didn't leave sona for another girl.
Again I am not justifying him .
But sona loves him!!
They are trying to bring the third/ jealousy angle -
Won't it take some time who are in deep love probably only one time in life- to come out of it ??
The time frame they should show- 2 days / 2 weeks later u are with somebody to get over Dev ??
That I cannot digest.
I am not saying sona should run back to Dev / lose her self respect:
She is shown to be the mature one .
She claims to know Dev inside out.
She should give some benefit of doubt
The way he was looking at her / the way he called her sonakshi- was very well reflecting his own self-
Let time decide- give some time to ur relationship-
Reasonable time before u jump into some other relationship.
Sorry , this is my pov.
