Tapasya has failed many times in her so called "LOVE" test...
1) She failed to change for Veer (in the beginning of her marriage fiasco) instead has busied herself in duplicity. She failed to realize that Veer loves honesty and not her skin deep beauty.
2)She isn't grateful to Veer for bringing her back to haveli thanks to her manipulation of Vansh instead she gloated her Victory. In love you are never victorious over your partner.
3) Big failure: She failed to save Veer from going to jail on Ichcha's accusations. She is the only one who knows the truth but still was busy saving her own skin. Its the Inspector's and Veer's intelligence which had saved him and the lady did nothing at all...
4)Tapasya's famous dialogue to Nani: "I don't mind Veer marrying anyone but it shud not be Ichcha" proves how deep her love is for Veer
5) She realized that the baby is Rathod's still going on saying that it to be Veer shows how deep her love is. If she had loved Veer she would definitely have told him the truth and asked his forgiveness. Only obsession blinds a person to the level of committing sins.
6) If she had truly loved Veer she wud have married Rathore when he said he will help Veer in exchange of their marriage. Any girl in her place wud have married him becoz thats the only way she can see her love's well being but here we see Tapasya going back on her promises. Its Rathore's goodness and fear for the baby that actually made him to help Veer or else Veer wud have been still holed up there.
She had never loved Veer. Actually totally obsessed...so where is the question of Test !!!
