My anchor partner gets upset when I accidentally call him by my fwb name or call my fwb by his name when talking about him to my partner. Let’s say my partner’s name is Jon and my fwb partner’s name is Evan. This morning, I was talking about how Evan is taking me to an event later this month to preface how I found a funny thing online that I was about to show him (Jon). I accidentally referred to Evan as Jon: “Jon is taking me to [event] later this month, so I was online looking for-“ and Jon cut me off to ask “Who’s Jon?” and I realized that I’d called Evan Jon, so I laughed a little and corrected myself, but he said “I don’t like that you do that” all seriously, and I got upset because we’ve had this conversation before. I told him (AGAIN) that he and Evan are the only people I have in my life that I’m not related to, so of course I’d mix them up. I left the room after saying “well anyway I was just going to show you that (online thing), so that’s all” and left the room angry. Later he came into the room I was in and acted like everything was fine again, so I did too, not sure if he is still going to be upset about it in the future because I’m sure it’ll happen again, since both “Evan” and “Jon” are in the “people I’m close to” box in my mind and it’s just as likely I’ll pull the correct name out as the other if I’m not thinking about it carefully every time I bring Evan up to Sam.

For some context, Evan was my boyfriend 4 years ago and we didn’t have much of any kind of relationship for a few years until we became fwb. I’ve accidentally done this in front of Evan as well, and he is so chill and dgaf that when I realize and correct myself it’s not even discussed!

It feels like Jon’s blaming me for something I’m not doing on purpose when he gets mad at me for misnaming him or Evan, which is why I get upset about it and don’t feel it’s something I should have to apologize for. AITA?
