I thought long on vividha will marry to whom? If vitharav marriage, then how they will separate ways? One possibility comes in mind, so I am sharing it. You can also share your idea/thought/story here for vitharav separation after their marriage.
My story:
If after confrontation, vividha will faint, then doctor will tell about her being pregnant to Atharv. So Atharv will decide to marry her. but when doctor will tell that , vividha is unconscious, so she don't know about pregnancy. When vividha will become conscious, Atharv will marry her and vividha will be happy after marriage. After marriage, Atharv will tell vividha that she is pregnant, so he marries her. After hearing this, she thinks like reason of marring her is responsibility, not love. So she will feel hurted and thinks that she doesn't needed anyone support. And will decide to go away from Atharv. It's like hum tum movie story.
I know , this is not such a good option. but after thinking many possibilities about vitharv marriage and separation, I think this is the only way of their separation after marriage. Beacuse both are fully responsible person and also love each other deeply, so they don't leave each other after marriage. But , if something like this happens, then vividha will not accept their marriage, she thinks, Atharv pitty on her.
For vividha her love for Atharv is always above her anger, so she can't leave Atharv due to anger. But if Atharv will hurt her self respect, then she can leave her, that is my opinion.
