Thats why when P will fall for RB she will understand the true meaning of love.I don't know but I don't see it as love. I see it as possessiveness. Even nivi see it like that. If prerna was to get married to any other guy anurag will come there and claim his right on her. His dialogues saying you belong to me; only I can put the vermillion on your forehead; no one can snatch that from me; I want her back I deserve her; she belongs with me in this house. That's not love but possessiveness. He views her as a property he can love as prerna put it. He is calling all the shots in their relationship like when he said when they get married he wants to have kids right away. He didn't bother ask what she thinks about that and prerna just goes along wiTh it. It's because of his forcefulness that caused prerna to get pregnant in the first place.
That love will make her say those things to Anurag.
When she will fall in love with RB, that will be visible thru her eyes.
Anurag will read it.
