I completely agree. This is Ovi's time to be happy with her child.
I am SO glad she hasn't told her family and Sperminator Arjun (if indeed he is the father). Frankly speaking, after Arjun's indifference and absolute lack of grief for the child he lost with Ovi, I cannot blame Ovi at all for not telling him. He doesn't deserve to know. And it's not like this child will make a much difference with him. He can create as many babies as he wants with Purvi using his super sperm.
As for Sperminator Arjun and Mahaan Purvi's marriage. Well we can make excuses as much as we want. "OHHH it's Ovi, DK, Manav, Deshmukh family's fault their marriage is at risk" The truth of the matter is that Arjun and Purvi are the ones married to each other. I don't see how anyone is setting out to ruin their marriage. If Arjun and Purvi cannot communicate with each other or understand each other, then it's no one else's fault but their.
Ovi is NOWHERE near Arjun/Purvi. She hasn't looked back at them ONCE and I am very happy to see this change in her. I am also glad that she hasn't told Archana because she finally knows that her mother doesn't give a crap about her. Archana will always blatantly favour Purvi.
