My Wife’s Brother Had Just Passed Away But His Wife Immediately Came And Made a Shocking Request —And My Wife Agreed Without Hesitation? What Should I Do?

The Backstory

After saving enough money, my wife and I purchased a larger, nicer house. We decided to keep our old home as a rental property since it was in a prime location near a busy market. At that time, renting it out could have brought us around $500 a month.

However, around the same time, my wife’s younger brother lost his job. His wife was pregnant, and their family had no income, relying entirely on my in-laws for support.

Feeling sorry for her parents, who were working tirelessly to provide for their children, my wife suggested we let her brother use our old house to start a business. I reluctantly agreed, even though it meant giving up potential rental income.

Her brother and his wife renovated the property into a hair salon, which quickly became popular and generated decent income. But over the past eight years, they never once showed any gratitude. They never gave us gifts, not even during the holidays. Whenever we gave their children red envelopes during the New Year, they would only return the gesture begrudgingly, and always with a lesser amount for our child.

Many times, they hosted gatherings with friends at the house, eating and drinking, but never invited my wife or me. I knew about all of this but chose not to bring it up to avoid creating tension in my marriage.

The Tragedy

Three months ago, my wife’s brother was involved in an accident and passed away in the hospital, leaving behind two young children. His passing was heartbreaking, and the salon closed soon after. His wife, who had only helped him with hair-washing tasks, lacked the skills to run the business on her own.

A week ago, my sister-in-law came to visit, bringing a basket of imported fruit. She asked to buy the house from us for $50,000.

Hearing this, I was furious and wanted to confront her. However, out of respect for my wife, I stayed calm and replied:
“I have never considered selling this house. My wife and I don’t need the money, and even if you offered $500,000, I wouldn’t sell it. This house is meant for my children’s future.”

To my surprise, my wife intervened, saying that her brother’s wife was struggling to raise two children alone and needed the house to start a small shop to support them.

The Argument

When I firmly opposed the idea, my wife argued that she had contributed two-thirds of the money to buy the house and insisted on selling it to her sister-in-law at a discounted price. She said that we were in a good financial position and couldn’t stand by and let her family suffer.

For the past week, my wife has been pressuring me to sell the house, even threatening divorce if I don’t agree. I am at a loss for what to do. How can I convince her to abandon the idea of selling the house for such a low price?
