Your situation is understandable no one wants to be put down and controlled by a sibling. However no one can really tell you what to do. As harsh and blunt as it sounds you need to pick your battles. Of course it is annoying , but if you can ignore it then do so and go about living your life. Honestly, from what I see you cant do much more. If you move out yeah you will find your peace of mind,but that will be a drastic step especially since you are from a somewhat conservative upbringing. Further you will come back to a pretty dysfunctional situation from what it seems like , back to being treated the same way, unless your brother wants to change he wont change and nor will things at home. Now how you deal with it is up to you. If talking to him is not an option or getting your parents to talk to him ,you will have to try and ignore him and just go about doing your thing.

Yes true...well I spoke to my ammi...lets see how it goes.
It's amazing to me what people call independence these days. How are you independent if you rely on your parents or brother for any kind of support? Do you contribute to anything at home or is it your brother and parents who get to have all "fun" responsibilities? Who pays the bills, looks after the house, does the chores at home? If you contribute in anyway to make their life easier, you have the right to complain. If you don't, you have ZERO right to complain. Everyone has their struggles. Just like you have yours, they have theirs. If anything, your single life is probably a lot easier than your brother's who has to take care of his wife, child, and your parents. You say your parents handed your brother everything or he would be nothing. Who does your parents expect to take care of them in their old age? You or him? You and I both know it's his responsibility to take care of your parents when you are long gone to your susral. It's common sense that they would invest in him. As bad as it sounds, that's how lame desi culture works.
I just had a long discussion with my friends about home and the unmarried ones were really disturbed how suddenly they had none. Their parent's houses were being saved for their brothers. Their brothers could be completely usless but will always be welcomed home a hero but the girls were getting uneasier and uneasier because it was constantly being implied that their home was elsewhere. They would not be acknowledged as adults because we as a society have a habit of pretending single women are infants. If you think the problem is bad then it's about to get worse as long as you stay unmarried and stay in that house. All my friends took off to separate continents and see their parents once or twice a year it got that bad. And if it was just a girl or two then I would think it was circumstantial but every unmarried one is having the exact same problem.
You've been demoted in your family because your brother is now not your peer but a married man. He's suddenly an adult while you won't be considered to be one. Talk to your mother and talk about how you can maintain a separation in the house. You don't interfere in your brother's affairs and he doesn't interfere in yours.
