After the bhayankar dream, looks like Raavi decides she will marry only with Shiva's consent. Hence the dialogue in the precap.
I think BhabiMa's Khurafati dimaag asks her to go ahead and get ready and she will take care of Shiva'a approval.
Looks like BhabiMa failed again because Haldi is being done for Hardik Bhai who is not even going to get married 😆
It will be interesting to see how BhabiMa makes Shiva agree to sit for haldi.😕
