Night, I think you need to express to her the exact same message you gave us here.
You don't know this guy, so you're in no position to advise her one way or the other. Tell her you'll be there as her friend no matter what, and that you wish her well. Just assure her that she has to be herself, and if this guy can't handle that, he isn't the guy for her.
Don't take too much of this onto yourself. It will backfire just like you suspect.
