Right after the divorce procedures were finalized, I arranged for my mother-in-law’s hospital bed—along with the 3 billion VND worth of medical bills—to be delivered straight to the mistress’s house…

Standing outside the courthouse with trembling hands, I felt an odd sense of relief. My ten-year marriage, filled with tears and countless wounds from my husband’s betrayal, had finally ended. But there was still one thing left for me to do: return to him the responsibility he had been avoiding all along.

My mother-in-law—an old, frail woman—had been bedridden for more than two years. From the moment she fell ill, I took full responsibility: preparing her meals, watching over her sleep, handling every pill and every hospital visit. My husband, too busy with his mistress, hardly cared. I endured it all, holding on to the idea of being a dutiful wife and daughter-in-law. But the day I caught him openly bringing his mistress to a hotel while I was at the hospital taking care of his mother, my heart turned cold.

After the divorce, I rented an ambulance and had my mother-in-law’s hospital bed transported directly to the luxurious house where my ex-husband and his mistress were living. Along with it was a thick stack of medical bills—over 3 billion VND, money I had borrowed from everywhere just to keep her alive. I could no longer carry that burden. The son she gave birth to had to take responsibility.

When the ambulance stopped at the gate, the mistress opened the door, her face bright and cheerful at first, then instantly pale when she saw the medical staff carrying the hospital bed inside. My ex-husband, just coming down the stairs, froze in place as if struck by lightning. I handed him the pile of bills, my voice calm but firm:

“From this day on, I am no longer your wife, and no longer your daughter-in-law. Your mother is your responsibility now. These are all the expenses I’ve already paid. The rest, you will handle.”

The room fell silent. The mistress whispered nervously:

“This… this isn’t my responsibility…”

My ex-husband grew angry, but he had no way to refute me. He knew very well that without me, his mother wouldn’t have survived the past two years. I looked at her—her eyes clouded yet glistening with tears. Her hand trembled as she grasped mine, her lips moving but unable to form words. I bent down and whispered:

“I’m sorry, I can’t continue anymore. But don’t worry, I’ll still come to visit you often.”

Then I turned and walked away. But little did I know, the story didn’t end there.

Just a few weeks later, I received a call from the hospital. They said my ex-husband had failed to pay the bills on time and even lashed out at the staff. The mistress used the excuse of being too busy to care for his mother, and at one point even raised her voice, refusing to spend money on a private nurse. Since all the medical records and contact information were under my name, the hospital had no choice but to call me.

I was shaken, but I couldn’t abandon my mother-in-law. Once again, I had to find a way to manage. Just when I was at my lowest, a middle-aged man came looking for me. He introduced himself as an old friend of my in-laws who had lost touch for years. He said he learned about the situation through neighbors and wanted to help. Then he revealed a secret: my ex-husband had once borrowed a large sum of money from his family—money he never paid back.

I was surprised, but then I realized: it wasn’t just with me—my husband had always been an irresponsible man, even ungrateful toward his benefactors. That man decided to sue my husband in court to reclaim the debt, and at the same time, he promised to help me care for my mother-in-law, since he regarded her as his own sister.

During those days, the mistress gradually revealed her true colors. She couldn’t stand having to serve a sick, bedridden old woman while money kept draining away without any benefit to herself. Just a month later, neighbors were whispering that she had packed up her things and left, abandoning my husband and his paralyzed mother.

As for me, although I was no longer bound by law, my heart still ached. I decided to bring my mother-in-law to live with me in my small rented home. I wasn’t wealthy, but at least she would be properly cared for and not abandoned. The day I brought her back, she gripped my hand tightly, tears streaming down her face, her lips trembling as she whispered:

“You… are my daughter…”

In that moment, I understood: even though my marriage to her son had ended, I had found another bond—one far more sacred and genuine.

As for my ex-husband, when he was finally faced with mounting debts, the betrayal of his mistress, and the condemning stares of society, only then did he taste the bitter consequences of his infidelity and irresponsibility. But by then, it was already too late.

This story taught me one thing: sometimes, the sweetest revenge is not in making the other person suffer, but in simply returning to them exactly what they sowed. I had let go of the burden, found peace again, and cherished the motherly love between me and the woman who once was just my “mother-in-law.”
