A Celebrity Kicked Us Out of Our Table

Somebody tweeted this. This is a super long story. Basically, me and my best friend hooked up with our other best friend's ex, and I don't know what I should do, if anything, or if it's fair for them to not be friends anymore. Okay, I'm gonna go into the story. It's really long. Here we go. So basically, one of my best friends, let's call her A, had her first major boyfriend this year. They dated for 6 months, and it was A's first kiss and other stuff, but I mean, dot dot dot. And A loved him, but they broke up and it was really bad and he wasn't who A thought he was. Okay. While they were dating, one of my other friends, let's call her B, was flirting with A's boyfriend so much that A had to confront B and her boyfriend about it, even though her boyfriend was clueless. A and B also had problems before and it was a kind of a toxic friendship. Then, 2 weeks after A and her boyfriend broke up, C— Yes! D, or C, started eating B out. B was hanging out with him at her house and they hooked up.
