Best part is when, over the phone, Gauri tells Shiv he can compelete all his important work and then come to meet her. He says, "Mein abhi aa rahaa huun. Gauri, tumse zaruuri aur kuch nahi hai mere liye". This when he had to accompany Ipsita to her mother's house.
Shiv should also take a strong position against Gauri's unreasonable demands. He should have downright refused Gauri's demand that he go to pick up Ipsita. (Well, how could he marry again in the first place).
He should also be stern against his family members. Like when Mahen says, "Why did you marry Ipsita if you cannot accept her." Shiv should have said, "Why did you and family members pressurize me, father?" Somehow Ekta's character's are sick with this "family" virus.
