Definitely... I am not blaming Daya there. I am actually blaming the writers. I can quite understand his POV. He might have feared rejection so he did not confess directly.
Neither am I saying that Abhijeet was right. He definitely did a huge wrong by not revealing everything to Daya.
Basically, I was hell annoyed because they did not show a direct confrontation between the two... Instead, they showed Daya passing comments regarding his friend being a backstabber and other stuff.
They could have shown one scene where Daya was directly asking Abhijeet the reason why he hid all this and Abhijeet blurting out the truth unknowingly as he promised Shreya's father that he won't reveal anything...
They were definitely inspired to introduce a full fledged romantic track...
As far as the verbal abuse is concerned, people say a lot of things in anger but ITV loves to stretch it beyond the point and make the characters look like villains. So I can totally get your frustration.
This is my main issue... Yes, a lot of people say a lot of things in anger. But, ITV stretches it beyond the point that it makes the characters look like villains... That was what I hated the most.
As far as Shreya is concerned, she wasn't wrong to give speech on friendship. A lot of times it so happens that a third party can actually state proper points which in extreme anger we overlook. 
But ITV has always made it look like the heroine has to save the day while years of friendship meant nothing.
So again I get your frustration. 
Exactly!! This is exactly why I was hell frustrated... 
Yes, a third party can actually state the proper points which we overlook in anger. But they made it look as if the heroine has to save the day...
