Ask impersonal questions and try to be a good listener. By just being a friend to her she may open up and talk about things... or she may not. But at least if she knows she has a friend in you, and can count on you that would be good.
Like others have advised, don't try to rescue her. Just try to be a great guy who she can feel comfortable talking to. Hopefully the R with OM won't yo-yo and he won't come back. Hopefully he's done with her for good.
There is no arriving, ever. It is all a continual becoming.
