I think she feels there is no need to defend herself..she has made her decision and everything else is unimportant at this stage.
But that's Laajo though...she does not blame others,never points a finger at anyone.And right now she is least bothered that Ishana and Barkha knew about her decision and did not bother to tell Nikhil or anyone else.And I think that's the reason why Laajo told these two women cos she knew they would not tell Nikhil(for their own personal benefits) and that's exactly what she wanted,Laajo did not want Nikhil to know cos he would have tried to stop her and maybe she would have given in to his pleas..it would have been really hard to stand infront of Nikhil and tell him she is leaving.But im sure one day Nikhil will learn of this fact and he will realise how much Laajo sacrificed for him.
yes i completly agree with ur views . There is no need to defend herself anymore to anyone
