To keep it short, my boyfriend ended up fighting with me about this. At the beginning he didn't say he was mad but he asked if I would be bothered if he had a girl over at his house to study. But he mentioned a specific girl; he mentioned a girl who he used to talk to.
(To help you better understand: my guy friend, my guy friend's cousin, and my boyfriend are all on the same sport team and I'm close with all of them and they're all close to each other.)
In the end, it's all fine. We fixed everything. But the fact that he even brought up a girl who he used to talk to when I don't even talk to her or am friends with her and she had not a single thing to do with the conversation still bugs me. Am I wrong for thinking this?
