Misunderstanding with my boyfriend, please help?

My boyfriend and I have been together for 2,5 years. I am loyal and so is he. We love each other and trust each other. We are confident in our relationship and don't really get jealous or worry too much.

But a few days ago a misunderstanding happened. I often play the game fortnite and I was playing the 'delulu' mode on my own. Meaning that you can talk to everyone in the game. It can be toxic, but also really fun. After 2 hours I was in a game full of Dutch people (I am Dutch) and we all got along and had fun. Girls and guys. The group of around 10 people invited me to join their party so that we could play more games together at that time. They all added me (and each other) and I added them back. Guys, girls, I didn't really care.

30 minutes later I logged off and after that I never spoke to them again. Yesterday I was playing fortnite with my boyfriend and suddenly one of those guys (from that group) randomly joins my party without asking or letting me know. Mind you, I never personally spoke with this guy, he was just in that group for the 30 minutes that we all played together. I literally didn't even know his name lol. Already forgot about that group in the first place.

For some reason this guy did know my name (It's lowkey in my username, but he said it as if he knew me very well, and in Dutch). He could also see that I was playing with another guy (my boyfriend), before he joined. My boyfriend went silent and asked "Who is this?" So I kicked the guy from our party without talking to him and immediately unfriended him. I then explained to him what happened in the delulu gamemode and that they were all Dutch aswell. He seemed to believe me, but the rest of the night he was more silent than usual and I could feel that he was a little uncomfortable and perhaps even sad? Eventually he cheered up again and bought me a skin, but I just feel so bad that I made him feel that way, even though it was a huge misunderstanding.

What do you guys think?
