@ ChemistryMajor- good to see you again!
I think you have really good points.The parallels between Ankita and Purvi are striking.Both left during pregnancies and into oblivion because they wanted others to be happy (same old sacrifice theme, even though I am not too much against it if done in a dignified manner without melodrama). Yet there are some differences in the tracks that make things complicated.Purvi's being an unwed mother does not seem critical because most of us seemed to agree that the circumstances of conception should not impact the child. It is never their fault and each child should have equal rights and dignity regardless of in what circumstance they were conceived. In that track, Arjun actually loved Purvi very much, so he was not going to deny the paternity if the issue ever came up. Further, Arjun-Purvi were engaged - so there was a basis for their intimacy. Purvi's leaving was an act of sacrifice.In Ankita's case, she also left - to a degree as sacrifice; but to a degree it is also a pragmatic solution to a very messy situation. She was a wedded wife all right, but to the insane but sweet Naren who loved her as Ahana. Ankita never existed for him. The new Naren - who is a completely different person and is madly in love with Pari - abhors the idea of having anything to do with Ankita . If he came to know about his paternity, he would badly insult Ankita and accuse her that she seduced an insane man. He did not wait to jump to conclusions about Shashank being a father just from Ankita's statement that she had loved Shashank. Additionally, the contract that Ankita was tricked into signing by Rushali has legal value. So, all in all it is such a messy situation that in order to allow two people in love to be together and avoid any further insults for herself and her baby, it is good for her to go away and not accept that Naren (who is an entirely different person now) is the father.As for the baby's rights, if the father saw the baby only as a symbol of his helplessness due to which he lost the love of his life - what good is it for the baby? Being raised by Anikta as a single mother, the child will not have the privilege of money, but a strong woman like Ankita can raise the child with good values and dignity as did other women in this show.
