I completely disagree with you. Even after Ridzi found out about her adoption, she still showed the highest respect and love for her father. If she didn't love her father wholeheartedly, she would have ran away with Armaan or left Shanky when he was against the relationship.
As for the love Armaan had for her, I agree that it was and always will be great. But Ridzi's love is also great, I think you all easily forgot the bullet and the times when Armaan lost his memory and unknowing said hurtful things. The only reason why she comes off as wavering is because of the constant lies everyone says to her, first the adoption, Muskaan-boyfriend thing, and then Pari. The anger on Shanky was just the huge trash that she always received. But before this, she never said anything against anyone. From this one lie, her whole life just left her and she was disappointed to know that her father didn't even care about her tears. That is the only sign of self pity I've ever seen, and if it were any other girl she would have commit suicided a long time ago.
Seriously, most of the people here don't even deserve to have Armaan and Ridzi back. You guys just continue to bash her and not look at what Shanky did. Sure she believed him, because she said she tried to look for him and plus, she trusted her father. If that's not love for a father, then I don't know how you define love.
