Where does the question of Aakashi divorcing Shamardas occur?
Its an illegal marriage in the first place! You cannot kidnap someone and force them into a marriage, without any witness present!
I don't think Shamardas has any interest in living with Aakashi, he hates her as much as she hates him...he married her only to break her arrogance and take revenge...it was more of a show of power and supeiority than any intention of marrying Aakashi!
PS : Aakashi is not a sweet, innocent girl, btw! What happened with her was very wrong and she definitely does not deserve it...but she is not a sweet girl, for goodness sake! Her character is very arrogant and high-handed and she kept rubbing Shamardas in the wrong way instead of minding her own business!
