One of my friends started dating this dude a couple of months ago, overtime we meet his friends, we thought they were chill and now it just turned into a big friend group now. I have recently been going out with one of her boyfriends friend and it has been fun, but then my friend and her boyfriend started sharing their unwanted opinion about my situation with him, I told her in a polite way to fuck off (same with her boyfriend), mind her business but then she got mad at me and said that if things don't turn out well the friend group will have to "disband" and that I would ruining the friend group, and that if she has to choose between two friend groups she will choose her boyfriends (mind you we have had our friend group for more than 3 years, way before her boyfriend was in the picture) I don't consider myself to be wildly immature, and I know that if things don't work out we are not gonna hate each other, I told her that. But ngl, it feels like she wants things to go bad to prove her point.
