Posting from a burner account just in case. I (24F) used to be best friends with a guy, let’s call him Aaron (25M). We’ve been best friends since summer of freshman year of high school, so about 10 years. We were super cool throughout high school and even when I went away for college. I moved back after a year and about another year after that he meets a girl, we’ll call her Sarah (25F). Sarah and I hit it off really well, and consider each other best friends. As their relationship goes on, problems start to come and she constantly vents to me. This puts a strain on Aaron and I’s relationship, because as much as I tried to stay out of it, the things she’d tell me combined with the things I’ve seen him do sheds a new light on him that I’ve never seen. Things like calling her ugly, saying he’ll find someone else who can give him better sex, telling her he doesn’t love her, etc. Without giving too much detail, he’s in an industry where he encounters a lot of women, and let’s just say he’s not the best at being faithful, not trying to hide it. Over the past year he has changed and has turned into such a cold hearted cynic who only cares about himself. He’d blow off plans we all made, ignore calls, and subtweet people on Twitter to make himself look good for his industry colleagues. Up until this year I tried to be a good friend and a listening ear for Sarah as things slowly started getting worse. But after the deterioration of our friendship over 2020, and him missing my wedding, I no longer want to hear about her and Aaron’s issues. It’s emotionally taxing on my part because I know the person that he used to be, and I’ll be honest, I HATE the person he is now. Even hearing his name disturbs my mind and genuinely upsets me.

They’ve recently broken up and I gave one final piece of advice to her, hoping she’d see the person he is and the way he treats her. But now they’ve gotten back together and I know the inevitable is coming; her crying and calling me wondering what to do. I don’t want to to hear it. I don’t want to to see snapchats of them together, I don’t want her sending me screenshots of their conversations, nothing.

WIBTA if I ask her to stop talking about him with me? And if so, how do I go about asking without sounding like a complete twat?
