Nahar obessed? or depresseD?

Hey guys

what i dont understand is i know nahar killed his wife in what circumstances i dont know but if he didnt like his wife anymore and killed her why does he always go to purani dodi? i mean he comes out all serious what does he do in there?😆 It confuses me there that he is so protected about the key he has a new wife but is kinda cheating on saloni by going in there.
