Re: Is it right?
There is no reason for you to be confused. If this was a love marriage where you already knew the guy personally and had actually fallen in love with him and knew in your mind/heart that he is “the one” for you, then I would say fight for him. But this sounds like a semi-arranged rishta where you don’t have an emotional connection to him. In these types of situation, you simply need to ask yourself whether the drama that will be caused in your family is worth marrying the guy. It doesn’t matter if your dad is right or wrong. He feels what he feels and nothing you can say or do will make him act differently. You, as an adult, simply need to decide whether marrying that particular guy is worth causing years of arguments/tanay/tension within your family.
In this specific situation, it sounds like that the decision has already been made to NOT pursue this. Once a decision has been made, move on.
