Sometimes all you can do is sit by and watch her make a fool of herself and then help pick up the pieces afterwards
My sister is a prime example there was no telling her at the time as she 'loves him' but then when they split up and he has run off owing her �60k - what do you do???
As you say you risk losing her friendship if you meddle too much. Just try and calm her down a little (not in a pushy way) and hope it all works out
