Jai has committed a huge mistake but he is human after all and to err is human, right. He is no krishna and no Ram . I guess what Bani meant while comparing Jai to Ram was not that he is her God or something but that he is one person she looks upto as a moral human being, a man with principles and values(it is another case that she will no longer think the same about him once the ONS comes into light and it is very much sure that his D-day is not far away )
Priyanka,i agree with your point that Bani may turn nasty towards him but at this point of time I think Bani is causing more damage to this man than imagined . She at every step decides to keep secret from him regarding things which can break or make this man. Jai just made one mistake but she keeps on repeating the same time and again. I believe she should punish him but what about all the things she made him go through and is still doing so.
