if it is not possible for writers to show that anupama doesnt go to shah house, then they should stop showing those abuses and stop showing anupama giving bhaashan that she will not return bla bla blah.
Make her say that she is a doormat and no matter how much they insult her, she will come back. and Stop her bhaashans about how all the kids are like her kids, because other kids and husbands are not like her family at all.
she can go back keeping her self respect intact if they want to show. In that case, she should stop doing baa baa when her little anu and current husband (on paper, not by dil se lol) are insulted.
It makes anupama look like a hypocrite that she says one thing and does other. It gives a message to all abusers that it is okay to abuse woman of their house as she will continue to be their doormat.
It gives a message that women should continue to worship her in laws and ex husband and kids even though they treat her as worse thing on the planet.
