because even when Delnaz frnds used to come home to meet her , he would have flirted with them and also embraced them sometimes that Delnaz never tolerated and finally there has arrived one day in her life she thought to divorce him...
even though they are both sent to big boss to make up with each other , i don't think Delnaz will be able to do that , as Rajeev is still doing same stuff he did earlier ( even though , hugging and talking with female inmates is just to make her jealous.)...
