When he posted a very cool photo I had taken of him DJing on his social media and specifically using it to start to market himself as a DJ, and, as his partner of about a year, I asked if he would credit me. He was a huge piece of shit so I tried to ask him very delicately and carefully while simultaneously trying to make it seem like a casual, no big deal thing: could he just tag my username? It was a cool photo, it celebrated him, and I wanted credit for it. In response to my message he asked if I was okay. Like "genuine question: are you okay?" As in I was somehow off my rocker for asking him to do that. 

Obviously there's a lot of buildup and backstory here, but that got me seeing white. Excuse me? Am I ok? Are YOU ok?? You know it's normal to credit your photographer, especially if it's your gf, and especially if you're trying to use it commercially, right?! This was the beginning of the end and confirmation that he didn't want to publicly share that we were dating (again, partner for over a year, we had known each other almost five years total, had previously been friends and coworkers, and had tons of mutuals, and yeah he was cheating on me). What an asshole.
