1) Nandini never wanted to get married to Ansh, she was tricked by him.
2) Ansh was violent towards her and high domestic abuse occured; out of rage, Ansh raped Nandini, which resulted in the conception of Bhoomi (yes Bhoomi, you ARE a product of rape!)
3) Finally, Ansh never revealed about Eklavya to anyone in his family, until the death of Eklavya's mother, Shraddha, who requested them to come somewhere far from Shantiniketan and take him, as he was going to become an orphan.
