I never felt that she is irritatingly childish..!!!!!!!!!! she is ok with her age of 19..
Relationship between husband and wife as our own aksh words is too personal... so you will find the difference in her handling her husband as well as other members of the family very different... you cannot compare those relationships at all. She can be stubborn with her husband, but she cannot be stubborn with other members... in married relationship husband is the one who should know you in and out, not others...
What is irritating you here is the fact that she is yet to confess her love and you are in love with character naitik and you feel that it is not right...
But looking at the other angle...
I can say, Akshara is right too, it is not easy to confess ILU so fast when a person is so shy... it is difficult and i can understand her stand completely... and i am sure this person is going to confess not when naitik is asking her, but when it is really required..
An example I can say is that if gaya3 talks to naitik about his job refusal and he gets upset, and I am sure that time akshara going to say the 3 magical words... what I mean to say here is that she need a situation to come out of her shyness... here she is going to overcome that..
She is the kind of character who does not waste her words unnecessarily... when she say these 3 words, that will have much more impact in his life than simply saying ILU at SR1 or SR2 or any other occasions..
It is not that she does not wanted to confess, but always the situations taken different mould whenever she was ready and naturally it might have put her off...
She is not going to be silent if naitik's zidd is not right or for unnecessary reason, she is going to take her stand... but if she thinks he zidd is right, you can expect her to be silent and supporting him.. Just my 10 cents..
