We all think Gauri's decision is not a good one, but think of her circumstances, she is dejected at that moment.
What she said to Shiv, was right, this is what u wanted right, so accept it.
Even though she is sad, but this will just bring them closer, nothing else.
Now daddy too cool's accident, this is too much, he can't die, Shiv will go to jail and do u really think Devika will save him. Devika is playing with Shiv too, one fine day Shiv will find out gauri is her grand daughter and he will faint at that point.
