I feel embarrassed because my wife left a high-paying job to sell food

I am 35 years old and work as an office employee, earning about VND30 million (US$1,179) a month. My wife, who earned slightly more than me, worked in the same company, though her job was highly stressful. She frequently left home early and worked late, often until 8 or 9 p.m., preparing financial reports. We’ve been married for 12 years and have children in elementary school. Despite the pressures, we diligently worked and saved, eventually buying an apartment and ensuring our children received a good education.

One day, my wife mentioned she was bored with her job and wanted to start a business. Initially, I thought it was a temporary phase, but she was serious about quitting. I supported her, though I was skeptical that selling sticky rice, banh mi, and porridge could replace her steady income. Nevertheless, my wife worked tirelessly, rising at 4 a.m. to prepare the food herself. Her stall gained popularity, and the income was decent.

Despite this, I struggled to discuss it openly. When asked about my wife’s occupation, I hesitated and vaguely mentioned she managed a small business. If pressed, I would swiftly change the subject. Embarrassment gnawed at me at the thought of our friends and colleagues knowing she traded an office job for a breakfast stall.

Moreover, watching her toil—getting up early, preparing, selling, and bustling about all day—I missed seeing her neatly dressed for her office role. I wonder if my discomfort stems from selfishness, but I certainly wish for her to return to her corporate life.

I share these thoughts hoping for some understanding from the readers. What should I do?
