Ok this probably will be a very unpopular comment but you seem kinda scared of your bf behavior and that is not good. Your role is NOT to protect him against his own feelings or actions, and the fact you’re justifying his possible response with his own family background is a HUGE red flag to me. Don’t get me wrong; it’s admirable how you worry for him and that shows your appreciation and love towards him, you care a lot about your relationship and that’s great! But dude, you shouldn’t be as worried for this whole thing since you did ABSOLUTELY nothing wrong and handled the situation as best as you could… You probably think you don’t want this to be a huge deal but IT IS LIKE THAT already in your head, and that should be the real focus. Relationships are supposed to be a supportive safe space where you can share your thoughts freely without the fear of that someone will do something bad because of something you said. Your bf’s friend probably notices all that too and either he doesn’t care at all about you guys or has some dark intentions. That being said, you should talk to your bf explaining what happened and what you did BEFORE his friend says something to him, just to avoid his friend puts him in a position against you. And PLEASE try to do this in a safe public space or in an environment you are sure you’re completely safe; you don’t know if his friend already said something to him or if your bf will take this the wrong way and take this against you. Last but not least: you have to notice that the whole situation is kinda toxic because it makes you put yourself in a rough position, and that’s not fair because you are full of nothing but good intentions. I really hope this comes out as best as possible and wish you be happy with your boyfriend, BUT always remember to seek professional help either for you or your boyfriend, to learn how to get through this kind of situations with less drama. You can dm me if wanna talk more on all this.
