The way I see it , it was manav's decision to replace her with Shravani .And he had a reason of doing this ..He had lost his jawaan brother , about to divorce his wife and was desperate to save the baby . Archu understood this and she stood by him .She knew that her family was responsible for bringing so much misery on the Deshmukhs and Shravani ...
Anyway , she has paid her dues . If she made a mistake she did not dump her mistakes on someone else ...she paid the penalty herself , she took the repsponsibility of those mistakes ..Even today she is taking the responsibility of her actions and I freally respect her for that .The only thing I don't like is the way she is still interested in Manav and Shraavni's life and I hope that this goes down with time and she starts focussing on her own life ..Move on ....😉
