Seems I missed an interesting discussion.
IMO we can't judge Suraj by his initial reaction, he'll realize the truth once he thinks it through, just like in Banaras track where he initially believed Imli then went to search for Chakor, there is an initial doubt followed by return of trust.
I don't want to drag old tracks but when her sister who everyone thought was good tells him that Chakor married someone else and then he sees the name of this man listed as her husband in the hospital records, he isn't to be blamed in thinking she moved on and yet he still searched for her to confront her, it was Suraj who sought out Chakor.
Anyways this accusation won't turn Suraj against Chakor, once he sees her life in danger he''ll forget everything even if Anjor doesn't own up to her lie which she won't she might confess to dak baba or an unconscious Chakor.
