Because Shiva and Raavi are not the leads and not important according to the writers. Of all the female characters, Raavi is treated the worst, no comeback lines, many times she lacks self respect, Suman constantly name calls her and physically abused her a lot especially during 3rd angle track.
Whereas BhabiMa is the center if attraction, from writers to even the last man working in the crew thinks BhabiMa carries this show and some if the cast members feel that too. Now along with Bhabima, Criminal is also equally revered.
Untli there is a sea change in writers views this is how it is going to be, Raavi will be at the receiving end and she will never get to defend herself and will be treated like a doormat, This is the right time to show Raavi taking a stand fir herself and file for divorce from Shiva. If they miss this chance, then her character is better being written off the from the show.
It's better to end raavi character. Even I am ok with both shivi character getting end. But we know Choubays hate raavi and can't make her strong character.
Leadben hone nahi degi. That's why I want this toxic show to end so that it doesn't doesn’t spread nonsense in the world.
