Thank you so much for your input so far. You are right, she needs to "fix" herself before moving on. I think she is still in love with the man she thought he was, but she knows that person doesn't exist.

He was, indeed, too good to be true.
From what I've been reading (here and other sources), good advice to anybody would be SLOW DOWN!! Don't get "into" a relationship with someone you don't know. That's what happened with my friend, I think. It all happened really fast, swept her off her feet (as they used to say).
