I'm not against his lack of mistrust, but his hypocrisy when he demands the same with Riddhima. She is lonely in that mansion where almost everyone is her enemy. So her trusting him is much more difficult than him trusting her
Muskie Ridz truth is just related to her personal life that is Kabir n the mission
And Vansh suspects her to be a spy so he was investigating mostly to safeguard his family.
Vansh confessed about Rags readily that she was his fiancee n owned up that now that chapter is closed.
But earlier most of the times Ridz would just keep quite n now finally when she started making an attempt to voice out her truth
but Vansh somewhere had started trusting her so stopped her not wanting to complicate their life n relation further
But Ishani's plan somewhere ripped open his past wounds of betrayal!
We need to understand one thing as of now that
Ridz is a orphan but her life seems sheltered cos nothing unpleasant apart from her lonely life has been divulged to us
but Vansh has a very troubled past so reactions will differ!
