I dated my girlfriend for 2 years, Everything felt normal. One night, her phone died, so she used mine to text her sister. Then she went quiet. She looked at me and asked, “Why is my number saved as ‘Do Not Answer’?” I laughed. Thought she was joking. She wasn’t. I checked. It was real. And it had been like that for over a year. The problem is… I never did that. At least, I don’t remember doing it. She then told me something worse. For months, she felt like I ignored her calls randomly, then acted normal later. I blamed stress every time. Now I’m looking at proof on my own phone… and I can’t explain it. I checked our chats too. Some messages sound like me, but I don’t remember sending them. I don’t know what’s scarier. That I did this and forgot or that I didn’t.
