Yeah but bk is not stupid. She knows the actual dynamics between people. She enjoys the attention of her devars, the fact that ninad values her word more than Ashwini. She may even have secretly enjoyed the fact that she got to go on trips with ninad without Ashwini- not necessarily in a romantic way (i personally find bk-ninad to be similar in some ways to virat-pp- and cringeworthy!) but just in a way to spite ashwini because she does not like her. In the initial episode she brags about how virat "values" her more than Ashwini. She wants to show ashwini that even in her husband and son's life she comes second. She enjoys the power n seems to get sadistic pleasure from hurting Ashwini.
It is possible for bk to ignore/overlook things deliberately for her own gain. So i dont think she is genuinely clueless about virat-pp history. She is just shown to be selective about acknowledging it or not as per her convenience.
In some initial episodes pre Sai coming to CN, she was stern with pp too. But she has become "sweet" with pp only because she hates Sai n Ashwini. And because pp staying guarantees money coming because as wife of samrat she is the next of kin entitled to samrats pension etc.
Do agree with this (to some extent) . However I think in future when everything is revealed properly, BK wont support Pakhi anymore. Her ghar ki izzat is more important than her sadistic pleasure.
