I have been in a relationship for 4 years with my high school classmate. We started dating in the 12th grade, and we've been together since then. Recently, we moved in together. I knew beforehand that he sometimes talks in his sleep, but in the past few weeks, he has been dreaming about talking to a girl named Maya. I discussed this with him, but he insists that I am imagining things because he doesn't remember such dreams. I've never had any issues with him cheating on me. However, I tried to find if there's a real girl named Maya he's talking to, but I found nothing on his social media except for an app called Deeva, where there's a character named Maya. I did some research, and apparently, it's a similar app to Replika, where you create a character to talk to via AI. It seems my boyfriend prefers talking to a robot and even thinks about it during his sleep instead of thinking about me. I don't know whether to laugh or cry.
