Every July, my husband left for a business trip to France—so for seven full years of marriage, we never once got to celebrate our wedding anniversary.
This time, I flew all the way to France to surprise him, and mid-flight, I stumbled across a social media post.
My dream girl finally agreed to be with me. How do I make the frumpy, worn-out wife back home file for divorce on her own?
The OP poured out his grievances in the comment section:
When my dream girl suddenly moved abroad, I married her former best friend to keep me company through the hard times, just so I wouldn’t lose touch with her completely.
Now she’s finally said yes to being with me, and I’ve made enough to give her the lavish, privileged life she deserves.
I want my wife to find out about my affair herself so I can get a clean divorce without a fight, but she’s so painfully oblivious. I’ve come home reeking of my dream girl’s perfume on purpose, and every single July I fly here to France for our private time together, watching the lavender bloom in Provence with her. She never noticed a thing.
Perfume. July. France.
Those matching details made my fingers go numb. A deafening buzz exploded in my skull. A bone-deep chill washed over me, and I prayed with everything I had that it was all just a terrible coincidence.
Until I read the final line.
Just got a spending alert from her supplementary credit card—she bought a flight to France. I’m heading to pick up my dream girl now, might as well keep an eye out for her, just in case.
The plane touched down. When I stepped into the arrivals hall, I lifted my head almost instinctively.
There stood Shen Sinian, the man I hadn’t seen in two weeks, in a crisp, tailored suit, a bouquet of roses in his hand, locked in a passionate kiss with a woman with a stunning, willowy figure, her back to me.
He opened his eyes by chance, and through the crowd of travelers, his gaze locked directly with mine.
