bold- yes most of Riddhima's fears are due to vansh's behaviouial changes towards her. And this is justifiedThe problem with Riddhima is that, she doesnt have all the 3rd person POV knowledge about Vansh that we have as viewers.
For her, Vansh is someone who forced her to marry him, doesnt let her be on her own terms, orders to wear his gift, yells and screams at her if she asks extra questions, even grabs her neck and pins her to wall if she upsets him. Not to mention, the Nariyal blast which has made her even more terrified of her.
He is romantic one day, burning her things the next day. He doubts her just as much as she doubts him. He thinks she is a spy and she thinks he is a criminal.
Given how Vansh was kicking her out of the house 2 days ago, her reaction to Vansh's sudden romantic behaviour is very normal.
People here grumble about how dumb Riddhima is (which she is, at times, no doubt), but she would have been truly dumb, if she had not doubted Vansh's sudden romantic advances and jumped into his arms instead.
Red- I don't feel she's dumb, most of the times she reacts in a natural way as a normal girl without any training as a spy would do.
Blue- I don't think she'd jump into his arms😆 no matter how hot, appealing or charismatic vansh is, it doesn't bother to her as she has Kabir in her mind(as of now)
Underlined- I don't feel that was romantic, poor girl was hell scared and he could sence that. Telling your wife to change NOW, giving her the gift you just burned some days before,.... doesn't give romantic vibes🤔
has she forgot to enter in vansh's life & then got married him despite getting chance to escape were her & her lovers mutual decision?
