I totally agree with you,his hurt was ckearly visible and today all the frustration he had erupted like a volcano,I know he didnt meant that they are actually hurt but hus anger made him say that ,He was equally hurt saying "We are done,We are iver" As much as twinkle was hurt.
I agree he has always given to the relation,and Its high time CVs shoukd not completely focus on thier Story build up although I agree with sid that thier romance has reached one step ahead but the relation needs to grow too,the secrets and the communication gap needs to be overcome.
I knoe twinkle is restrained too but I know soon she will tell him the reason behind doing all this and we Cannot say that she is wrong in hiding this thing from him because according her she is right the same thing what kunj felt when he hid the truth of her father from her!
