My two cents:
Anupama as a person has very tremendous respect for Baa and how much we hate it her acceptance means a lot to her. She has some morals and values which won't allow her to answer back or rebel against Baa! She would definitely go on to put up her points across, maybe go a bit on arguing as well but won't rebel like I'll do this joh karna hai Kar lo types until a point of tolerance is reached for her.
So all the other shoutings and dramas would be a build up for Anu to reach that level of tolerance where she would snap all the shackles and go all out on her love proclaiming it and rebelling for it (if front of Shah's or the world, we'll see)
If all these is coupled with a mini-separation from Anuj then her yearning for him may let that breaking point come earlier. Rest we'll see.
