I understand you viewpoint, and I am glad you brought this up 🤗
I personally have always believed in the importance of understanding self-worth and individuality. As daunting as it may be, living outside teaches you many important things in life. You learn how to interact with people outside of family, you learn independence, and at times you are forced to step out of your comfort zone.
There's nothing wrong with living at home. Shiva is cared for by the other members at home, he receives shelter and food, and if he is stuck in a situation, he can always rely on someone to help him. Unfortunately, I feel as though he is maybe too dependent on his family. He was coddled for most of his life, and as such, he doesn't know how to act in front of Raavi. Raavi had her fair share of mistakes, too, don't get me wrong. However, Shiva's mistakes are all mistakes that could have been fixed had he stepped outside of his comfort zone and interacted with others outside of Pandya Store.
As one of the owners of Pandya Store, he has a certain power he can show to his customers. If a customer angers him, he can kick them out. However, in his marital life, he cannot wield such a power. He has no right to pressure Raavi into signing divorce papers. He has no right to act in the manner he has without explaining to Raavi why he did all those things. Had he gone to college, or even stayed outside of his house, he would've learned that such actions cannot fly by with others... Outsiders are much less forgiving than family...
So this is one of the reasons why I want him to step out of his house. I want him to experience the outside world... the highs and the lows, because that's how you learn.
Furthermore, after watching this show for this long, I do feel as though the other members in the family (exception of Suman) take him for granted. They don't offer the same respect to Shiva, and by extension to Raavi. Rishita was never criticized for all the mean things she said. Instead, the family said she needed "time" and gave her a mango lassi. Meanwhile, Raavi was asked to "adjust" and "accept" the marriage essentially on Day 2. No mention of her almost suicide. No mention of the fact that she will have to live and breathe in the same house as the man who abandoned her in the mandap.
As such, for this reason too, I want Shiva and Raavi to leave the house. They don't need to cut off all ties, they need to leave and prove to the family that education + certificates are not the basis to determine one's "worth" in the family. They need to leave, so the family doesn't trap them in their current roles...
You're right, starting from scratch is difficult... but Shiva and Raavi have displayed an incredible amount of courage, stubbornness, and passion. Unlike Dev who gives up an opportunity, and Rishita who runs away when things are not in her favor, Shiva and Raavi both face problems head on... and I think those characteristics will allow them to survive in the world all by themselves. Each of them also bring a set of talents. Shiva has years of experience in the store. He knows the pulse of the customers, he is quick on his toes, he can negotiate deals... he doesn't need to be a laborer, he can try managing if he wants to. Raavi herself is also talented. She is educated, and if she really wanted to, she can use her cooking skills to set up a business. Shiva and Raavi could start afresh with a food truck business or a small restaurant or a home cooked meals delivery business.
Sometimes, you need to take the risk in order to get the gains... and I think in Shiva and Raavi's situation, leaving that house will allow them to lead a more fruitful and successful life than staying.
