Theres a huge difference between wanting ganga back than wanting nandini back.
1. Ganga was forced to leave, and Nandini left by choice.
2. Sahil had an extra martial affair with another woman, and Karan didn't have a choice if he wanted the well being of his daughter.
3. Ganga lost her identity by force, her children and status were taken away from her. Nandini gave up her children and status.
I'm not saying Nandini can't come back, all i'm saying is everyone wants nandini back so bad that no one thinks about wat will happen to tanya. Tanya gave up her whole life for Karan and Nandini, so she could take care of Nandini's family during her absence. As for the birth of Manthan, they didn't know Nandini would survive her coma. (it takes 2 not 1 for a pregnancy to occur, therefore tanya cannot be blamed).
Ganga was forced to leav by Gayatri. Gayatri didn't think for one moment that if she was in Ganga's place how would she feel and wat would she do. (Side Note: Savita was more supportive to Tulsi when Mihir and Mandira had an affar, Savita kicked Mihir out not tulsi; Gayatri should have learned from that example and should have better handled the situation). Tripti even shows her evil plans when she told sahil that if he got the contract she would take care of his family; then wat has she been doing for the last 20 years.
Difference between Tripti and Tanya
1. Tanya kept a family together; Tripti broke a marriage
2. Tanya was supportive to the joint family; Tripti showed bitterness towards all even "her children"
3. Tanya thinks good for all; Tripti wants to get rid of half the family
I just wanted to point this out because everyone shows sooo much hatred towards Tanya, and the whole issure with calling tulsi a hypocrite for not wanting Nandini back. No Offence to anyone
Tell me wat you think
