Nothing wrong with trying to help somebody.
My only comment, as I'm sure you already know, is that you're surely not the first person who's tried to help her. She seems to be a decent person, so she's likely come from decent family - probably a devoted boyfriend or two along the way, too. All have failed.
Of course, chances are that someday she might come around, and maybe now is the time. If you have the heart for it, give her what you can, but don't mistake the odds you are up against.
And +1 on keeping business and personal stuff separate...
