I changed my whole life for him. Clawed out of depression, doubled my income, held his family together. Then his ex sent me one message while he was in the bathroom.

A blunt proposition lands in her inbox from a man she barely knows. Then she notices who is smiling beside him in his profile photo.

He reposted our photo, called me from rooftops, said all the right things. On my birthday, a friend matched with him on a dating app — where he was very, very single.

I was scrolling the local rants page to laugh at someone else's drama. Then I saw the photo, and the comments started loading.

I ordered a surprise present for my boyfriend from the same little shop he'd been following. The owner read his name and went very, very quiet.

I was half-asleep, scrolling past a silly street quiz, when something in the blurry background of the video made me sit up and stop breathing.
