In short, he put his family in peril, making them insecure and uncertain. I get really annoyed when I hear about the luxe weddings people arrange despite it being well out of their means. Compromise a bit. Explain to Sameer and Arti about the honeymoon--give them a small one now and promise a better one later, one where they can even join them for a few days.
Don't get me wrong. I feel for Aditya. He does love his family and sister so much and works so hard for them. However, he made the mistake of thinking this is just about him--that he'll have to earn extra money, etc. to pay for the wedding. His decision impacts everyone in his family. He should have thought just a bit about his wife, daughter, and son too.
What do you think?
