I woke up to an alert from our home security system: “Back door opened. 3:04 a.m.” I checked the footage. I saw a man who looked exactly like my fiancé—same jacket, same figure. Except… he was asleep. I turned and wanted to wake him up, but then I froze when I saw his side of the bed empty.

I was about to get out of bed to search for him, but then suddenly my phone buzzed. It was a text from an unknown number. I froze as I read: “Just so you know, your fiancé leaves your house at this hour to see his girlfriend.” My whole world fell apart. I didn’t say anything but stayed awake the next day, and he left bed at 3 a.m. and went out. I confronted him, and he admitted that he had been seeing another woman for the last 2 months.

We broke up, and my life was forever changed. But I still have no clue who that text was from.
