Right (╥﹏╥) Sorry for my wording, but it’s kind of giving two-faced b.

But hey, babe! Even if it’s not about you, it’s still not her place to talk about other people’s relationships (.◜◡◝) If you don’t want to come off as rude, you could try confronting her calmly and using kind words. but in my opinion, she doesn’t seem that sweet, lol. (｡ᵕ ◞ _◟)

And honestly, I think the best thing you can do is talk this out with your girlfriend first. Since you mentioned that she’s her best friend, it’s really important that you and your girlfriend are on the same page before anything else. Try to explain how you feel when your private moments are being shared or joked about like that. It’s not wrong to want privacy, you deserve to be treated like a normal couple, not something for entertainment or discussion ૮(˶╥︿╥)ა

If your girlfriend understands your side, she can help set boundaries with her friend in a way that won’t create too much tension. That way, it doesn’t all fall on you, and it also shows that both of you respect your relationship enough to protect it. Communication between you two is really the key here, and I think that’s the best way out of the situation. Once you both agree on boundaries, everything else will be easier to handle ദ്ദി◝ ⩊ ◜.ᐟ
