Both are right in their places 😳
Purva hasn't seen her whole story, Riddhi has, she has seen her be happy, struggle with her feelings, almost get her love and then she has seen her tears and her pain has been felt by her too. So riddhi is right in asking her to forget Sid and move on! She's doing exactly what an elder sister does, although no one would be as happy as her, if Siddhant confesses, she's just protecting her fragile sister Anu and I love her for that! <3
Coming to Purva, she has always wanted the best for Anushka, she has wanted her to be happy and lately, she has realized that lies in Siddhant. Her advice is correct, that she needs to get her happiness but Anushka here doesn't have a clue Sid loves her, atleast conciously she doesn't, so she just keeps on hurting herself and helping out Sid in any which way she can. The point about sharing her feelings, well she already has.
So according to me, it's time for Siddhant to stand up, Anushka has done her part when it comes to confessing her feelings! 😆
