So she drugged her and left for Rajatan with Nahar. And from then on the woman who lived with Nahar's family and made all their lives hell were non other than Devika, not Chandni, but it was Chandni whom Nahar was married too. So technically Nahar is still married to Chandni, since Devika is dead.
But yes, what confuses me is that why is Chandni bad, Devika is the evil one who drugged her, then why would Chandni want to avenge the death of the sister who drugged her and kept her away from her husband. That is totally confusing to me. I don't have a clue when and how did Chandni become evil, because from all the flash backs that Chandni narrated it was clear that Devika was the evil one not Chandni.
