We were just having this discussion in the den again and here is what I typed there -
Here are some reasons why I think the CV's went with this way
1. A sense of equality in their relationship - Maan has always told Geet how important she is in his life and accredits all his current happiness to her presence. But in action, he has always treated Geet as a priced possession, something that belongs to him and never as a person. Her views don't care for anything, her thoughts are immaterial unless it is related to them. Geet has no say in matters related to their household and infact she is not even asked for a suggestion. Maan singh khurana makes the decisions. And when she made a decision without his consent, he questioned it. It is important for Maan to travel the journey and know the significance of equality in relationships.
2. He may never judge a person depending on how poor or rich they are, but he is very proud of his richness and hence thinks it almost his right to command and boss over others. It is important for him to identify himself without the support of his richness and his lineage, not because it is not rightfully his to enjoy, but because humility, humbleness and simplicity are important characteristics to possess and once that Geet cares about.
3. You sole a problem based on what created it. This time they have a problem because of him saying explicitly that his lineage is better than hers. So if he has to prove to her that he truly does not believe that, than he has to do it without its support.
