Here we have a girl with her whole family and even another home of her grandmother Sulochona if something goes wrong. A girl with 2 homes. She has a career. She also has a daughter to live for. What does Ovi have to live for? We have Soham disappearing and Archana is worried sick, but no thought to a girl who lost everything and has no support system. Sure you can blame Ovi for leaving but at times it is better to leave a situation that suffocates you (finding out that the child she took care of is her husband's nishani with another woman). It does not mean she can't use company to help her through it. How hard is it to hop on a plane when you have so much money? Why can't Archana go see her or even send Teju. I am also very disappointed with Manav for not even thinking about the welfare of his daughter and being blinded with love for his teenage wife.
It seems to me that Ovi is erased from the minds of D Clan and only brought up for specific purposes. Ovi going to the doctor's for stress-related pain signals to me that she has taken it hard. It would be of some help if her family came to visit her (minus Purvi since it would bring back too much pain). Even when she went to India she could not stay with her own family since the situation she has been avoiding was living right under the same roof. She had to live off a hotel without her family. This is a case of a girl being booted out of her family and no one is batting an eyelash - not even Savita who raised and protecter her like a lioness.
I would really hate to be a daughter of the Deshmukh's if it means getting the treatment Ovi is getting.
