When piyush removed his pagdi also, he told this dialogue which i can never forget and it was like " Aaj ek baar phir, Piyush Raheja apne dosti aur pyar ke beech haar gaya" If he wanted to back out of the wedding, he could have done that respectfully without all those dialogues of friendship. In a way he hung all those things over kashish's head, and it affected her decision. Prithvi is also doing the same. He asks Kripa if she truly wants to get married to him in one scene and the next scene he goes around buying houses and offices for her. I think deep down, he knows that Kripa still loves angad and that he's making a mistake, but is not willing to accept it. He still clings on to that Kripa who was out for revenge. This attitude cant make me hate him, but only pity him. Just as Piyush was fit to be pitied. Both of them in false hopes and not willing to see the true picture. But lumping Prithvi with a person like Piyush would be unfair as Prithvi backed off the first time. But piyush..ughh...thank god for small mercies.
