He Gave Me His Mistress's Bag, So I Threw Him in the Trash

I put the designer bag my boyfriend gave me up for sale on eBay. His younger sister, Zoe, saw it immediately.

She tagged me in the family group chat: "@Gwen, are you seriously selling a gift my brother bought you?"

"If you're broke, just ask me. Don't break my brother’s heart like this."

I didn’t reply. Her messages kept buzzing in.

"A bag worth thousands of dollars, and it's still not good enough for you? I swear, girls these days have no shame."

The bag was pre-owned. When I first unzipped it, I found a photo inside—a photo of my boyfriend with another woman.
