Soo I've been friends with this girl since last year September or so, we aren't bestfriends though, she's really open about whatever relationships she has, but I'm not the type to confide in someone else about my relationship problems you know , but she does know who my boyfriend is and she has met him before...

soo this is the part that I'm wondering if this is weird or not, I was standing with her and another girl and we were just talking about random things, soo my boyfriend comes up behind me and he greets me and tells me something infront of them and then I reply to him and then he goes on his way again , as I turned around, my friend literally rolls her eyes as he walks away and asks me "don't you ever get annoyed by him?" , I literally felt weird after that because I mean I never expected her to roll her eyes like that...

I swear they've never spoken to one another, they don't have each other's socials, nothing like that, it's just like they know of each other through me... Like is this weird or not?

She has made comments before about "how could you stay with someone so long? I could never" and even questioned me about our sex life on her own, like I didn't even bring that topic up, she straight out asked me when did we have sex and what positions we do, shit like that , I swear I've never actually had a friend before be interested in my sex life... soo I didn't know what to think about it

Just a reminder that I've been friends with her for months only and we aren't super close, we would literally only speak when we bump into each other or whatever...

Can you give your opinion on this?
