what should my brother do right now ?

So, my brother (35M) got married to a woman (34F) in 2021. Before getting married, they discussed that they would rent a place together and contribute 50-50 from their salaries, with the rest of their earnings being their own. However, it has been four years, and she has not contributed a single penny.

Due to this behavior, my brother feels extremely frustrated and considers it a huge turnoff. He is no longer interested in the marriage and feels like an ATM and a servant at this point.

For context, his wife has given him gifts on occasions like his birthday, but only very cheap ones. In contrast, my brother has gifted her items worth approximately ₹2 lakh, including a mobile phone and jewelry. She also does not send any money home to her parents, as she has a brother who supports them.

Additionally, my brother hired both a cook and a maid for their home, and she does not do any major household chores either. Because of all this, he feels like she is just using him for money.
