I sent a photo to my partner and she said she had never seen me before. What does that mean? Does she not love me anymore?

Perhaps for him, such photos are inconsistent with Rigami’s image. Maybe it broke through his cognition. To put it simply, there is no need to think so far. It shouldn't have any deep meaning. Of course, it could be a compliment. Whether you love someone or not depends on various behaviors in daily life and needs to be judged based on multiple factors.
