Burner account so my girlfriend doesn’t find this. I (24m) have been dating my girlfriend (26f) for a couple of months now, and things have been great. We immediately hit it off with each other, sharing a lot of the same common interests and going on a couple of really great dates. We started spending all of our time at each other’s places, and we've even been talking about moving in together. There’s just one complication that arose a few days ago, when we were fooling around and eventually going all the way with each other. I was about to finish and I knew she was too, but when she was hitting climax, she called out another man’s name. I was a little confused at first, and I didn’t really process it until after the fact. The name she called out was weird as hell too (Jerma). I thought she maybe just butchered my name since it also starts with a J, but it was also weirdly specific to be a random mistake. She seemed adamant about avoiding the subject when I tried to bring it up with her, so I stopped and kept it to myself for the time being. It was after she fell asleep that I searched her followers on instagram and twitter to see if this was some guy she had been talking to. The only thing I found was this account on twitter called “Jerma985”. The guy apparently has thousands of followers and is also on other websites like twitch and youtube. I didn't really know what to do with this information so I just kind of went to bed and waited to talk about it the next day. When that morning arrived, I tried just asking about the name again and she started crying and profusely apologizing. I wasn’t really mad, and I told her as much to help her calm down a little. She explained to me that this “Jerma” character is a “twitch streamer” that she follows and likes a lot, and it was a total mistake on her part when she yelled his name. She said she’s been obsessed with him lately, but that I didn’t have anything to worry about. I told her it was fine and that I didn’t mind as long as it wasn’t going to be a regular thing. The issue is, I can’t stop thinking about what happened. I don’t like seeming insecure, especially over this guy that neither of us have ever met, but it’s really weighing on me and I can tell our relationship hasn’t been the same ever since. Jerma is unknowingly ruining our relationship and I’m not sure how to fix it.
