where is khushi wrong and paying

for it? i know many women on this forum will not like my opinion for khushi. believe me i am woman definitely do not like other woman to suffer for mistake she did not did.
But here i feel that khushi is some what responsible for her current situation.
let me tell u why.
she was ok till the point she came to know about shyam. her decision not to tell anjli was right but she should have tell her any one else like nani, akash or arnav. i know now u will tell how she can tell arnav he would have never trust her or he would have emotionally broke knowing her sis marriage life.
But i will say here she is wrong she never understand arnav. She knows that arnav always think with his brain and at time if she had told him truth with involving her family. this make one thing clear that she and her family do not want to hide anything for that even they put payal marriage at risk.
Second when everyone happy that anjli is pregnant and arnav enter in room she fail to read his face and eyes which clearly saying he is not happy, in fact he suppose to be most happy for his di at that time.
And how come she can assume that after terrace incident that shyam will go back to anjli and everything will be normal. she should have talk to arnav about it. now not only anjli but her unborn child is in danger also arnav's life in danger.
She knows that shyam will not do anything to her.
So khushi fail to understand arnav in so many ways. she had notice change in his behavior, he never lie ( big proof la ) and always think from his brain.
