Dev just remembers that Sonakshi din give their relation another chance and she din believe her.
He has merrily forgotten how much she had tried to save their relationship, how much she had gone thru before giving up and actually she gave up was when Dev said Maa has told me take the decision whether or not to stay with Sonakshi. Sonakshi gave up bcoz she realised even now Dev cannot take a stand for their relation. She never wanted Dev and Ishwari to seperate but she wanted Dev to stand for them without Ishwari giving him permission to do so. Very logical! What if tomorrow Ishwari wld have again told to leave Sonakshi.
Dev is hurt and his pain has made him even more arrogant and stubborn. Dev still needs to realise this thing.
I really don know ne further redemption is possible for Dev because now he has gone into a blaming mode. Once v get into that mode redemption is even more difficult.
Precap is very disheartening. Both are victim of situation but Dev needs to realise right and wrong.
