The head of the family rejected Shorvori over class and caste difference. He readily turned his face away from every relationship between him and Parth. Non of the family members, except the younger brother and his wife, supported Parth's decision to marry his beloved. Clearly this family is as selfish as one can get! All they care about is their own pride, status and blood. I do not say that such families do not exist but i do not really see such families worth any efforts.
Parth and Shorvori are taking a huge risk by opting for physical intimacy between Parth and Teni just for a child.
I know they won't back off but it would have been better to back off from this whole surrogacy deal and adopt a child from orphanage. It's better to leave the house and live independently. If the family really loves Parth, they would soon accept his decision and understand the reason behind couple's decision to go for adoption. Parth did not exactly commit the biggest sin by choosing his own life partner. On top of that, Shorvori is not even a troublemaker wife. She has done her best to maintain peace and harmony between the family and son. Parth might had been rebellious about this aspect of his life but not wrong. The family is clearly overreacting and selfish! Parth and Shorovori are bringing a huge trouble in their relationship for some absolutely selfish and uncaring people.
If Parth's family can break relations over such small issues than they really don't know how to be a true family.
