Veer keeps saying it because at present ranisa is more imp for him . The promise is more imp than Rani. Like he said she will forget Veer with time as for both it was a forced marriage. It still doesn't count for him this marriage . Look at Rani so charged up about saving her father's land . For him it was just a piece of land .
Rani just entered his life . Ranisa was there right from the start or maybe when he was small. He is not a husband yet or Rani a wife . They r still both charged up only about their respective imp people in life . Writing his name was ok. It was a piece of paper . Marriage is entirely different . Ranisa asked him whether he was ready to spend his entire life with Rani . He was silent .
Rani also said to her father's photo , I always ran from marriage but went through the book rasam for your sake and dadisas sake . It has not sunk in both, the marriage part .
Right now what is happening to Veer is what happened to Rani .forced circumstances not happy to do it .
I believe a separation is on the cards as living together has not really made a difference. Rani will get her price of land but at a price, lose the marriage which was only on paper not really accepted with heart as filling somebodys maang forcibly doesn't really entitle a place in heart. There r some flutterings some cute moments but no heart connections or soulmate feelings so far. Rani has not really realised some thing is bugging him nor he her stand .just an opinion with no offence
