Someone who went trough trauma such as the one Imli gave Chakor (Chakor grow up with KN being her enemy, he was consistency in her life, something she is used to but she fight to end it coz better things can happen) because it was trauma in real sense of that word. Something Chakor didn't have controle over, unexpected and hurtful. Even after its over, it's let's say it like that, normal, for one to have fears and other kind of consequences. That's why I never really had problem with Chakor's nightmares. (Before Imli actually come out in open with Chakor.) Person should work on consequences and if needed take help also. One of the most important factors in recuperation after huge trauma is family support. Chakor had it. And if I remember good, after every nightmare Suraj calmed her down, not just that he talked with her about her fears, he was like her terapeut. But her condition got worse. We all know it was from justified reasons but Suraj doesn't know. That's the point where Suraj stops to behave like her terapeut and becomes her husband. Becomes angry and says she is mentally unstable but you see it on his face he regrets saying it while echos of words are still present. Gives her chances and when nothing is changing he gives her challenge. Like a husband and terapeut in same time. Gives her five days to prove him wrong and her right. His only intention is to give her time to convince herself her fears are not existing. Because he believes, in fact he is 10000% sure she will face her fears and realise they are imaginary ones. And everything will be good. Now tell me why he needs to accompany her? We can say because he is her husband. But wasn't he doing it all this time for whole year. Her state in his pov only got worse. Now why shouldn't he let her face her, again in his eyes, imaginary fear on her own because it's evident it's not going right way with his help? What I want to say.. Suraj should not accompany Chakor in her mission because he thinks the only way she will get over it is if she herself gets convinced there is absolutely nothing/ no one she should fear.
What happens after that, and how and why he becomes jealous I explained in other post my views.
(Am explaining Suraj's side of story here only because it's questioned, and because all this time after Chakor realised Imli is alive it's more easy to understand her pov)
We need to understand that Sukor are not just lovers, they are everything to each other.
The only thing that in whole story is making things overcomplicated and not so good is this insisting on recollecting friendship memories. I blame new/old writter. I understand she was in the show when it was normally for them to recollect these memories i.e. after 10 years leap till bride swap even after, but now in this situation it's only "damaging" Chakor's characterisation. It only makes her inconsistent and since she is fl it makes whole story much more complicated and less understandable. They could have find way to make Suraj jealous from the same reason without showing Chakor repeatedly recollecting her childhood memories with Vivaan. In fact in yesterday's episode Chakor and Vivaan could have had that high five without showing flashback. They could have shown it as something natural between them, Suraj would be still feel jealous and Chakor wouldn't be presented as woman who can't think about condition of her husband but can recollect her childhood memories. That way at least for me everything would be much more easier and understandable.
