I think part of Rishi's take back hisconfession of love in yesterday's episode has to do partially with this topic. I think her words to him about resposiblity and what can he do, hit too close to home for him.
I think those are the same words his father yelled at him before. I think his family never understood him and he didn't play by their rules (Sameers rules) and he finally ran out to america. He didn't want to play that dirty game. But hearing the same words from the woman he loves say that he is not responsible, that he can do nothing. No man wants to hear that especially from his love. To hide the hurt he made it a joke.
She's hurt when Rishi calls her out on her hitlerness cause everybody else says those things but she never wants to hear it from him. She changes topics when things turn to her issues with her father.
I hope they can grow to understand each other and know that what others say about them is not true and that they are unique individuals. and beautiful couple.
