[UPDATE] Me [23F] with my friend [23F], she cheated on her boyfriend/my friend [25M] and doesn't want to come clean

I decided to post an update even though the OP didn't get too much attention. Can be found here.
The TL;DR of the OP is basically this: My friend Sarah cheated on her boyfriend James, who happens to be my friend, too. She didn't want to tell him because he'd likely end the relationship and they had a big trip planned. I didn't know if I should tell him (my gut told me yes, definitely) or stay out of it.
After I posted here Sarah decided to tell James parts of the truth and told me to stay out of it. I decided not to do that since he deserved the whole truth.
I wanted to tell him in person but he couldn't meet up because he was at a family gathering or something like it, I don't remember. He called and asked me what I wanted to meet up for and I told him the whole truth. That she cheated on him with her best friend, that she didn't tell him everything that happened, etc. I was worried she got to him somehow and that he wouldn't believe me, but he thankfully did. I still send him every text I had of her, which was probably incredibly helpful.
While I was talking to him she sorta knew what was happening and drove over to his place immediately. When she got there he hung up and they talked. She tried to weasel her way out of it but since he had her texts that didn't work out too well.
Before she came over he told me this was the last straw, especially since she lied to him about it and made out with said friend once before. I don't know what she did or what she said, but he did a complete 180 and suddenly he was okay with it.
I've only talked to him twice since then and he told me that it's not such a big deal and they'd get over it.
They've completely cut me out of their lives, when I asked him why he said he wanted to wait until his girlfriend and I had a talk and could get along again - which isn't happening, since I don't want to be friends with her anymore.
It sucks that I've lost my two best friends even though I wasn't even the one who ****ed up, but at least I can sleep normally again.
TL;DR: I told my friend, he wanted to break up with her, she talked him into staying and they've cut me out of their lives.
