The other woman ?

Okay I hear arguments about Meera being the "mistress" and the other woman ..
"Mistress" are woman who KNOWINGLY involve in a relationship with a married man , seek help through finances .. They are basically KEPT
Meera is NOT a mistress , while yes she can be the other woman
Nandini can be the other woman for meera too
They both are equally affected by Ani's betrayal
Though we know Meera takes it well , but she had a lot of other experiences in life which kept her strong
Nandini has only known Ani , therefore she will be shattered when she learns the truth about Meera and Anirudh
It's not Meera's fault , Ani told her he would introduce her to his family and basically described everyone in the household except nandini
Please get your facts right , just because meera is wearing "western" clothes as opposed to Nandini's traditional wear she doesn't become bad or less affected by the betrayal of a man she loved

If she was actually a mistress she would reveal all about her relationship with Anirudh the day nandini came to meet her , money is the reason why they are mistresses in the first place
This woman lies to nandini for making her happy , she is lying all about her friendship with Ani and hiding the truth about the pregnancy
She is NOT a mistress , she is a beautiful person inside and out
