I would have had a lot of sympathy for her plight if she weren't using her daughter as leverage. That's just low, in my opinion.
She seems to want to both have good standing with the Orthodox community (otherwise, why would she need a get?) and live by the rules less strict that those imposed by Orthodox Judaism. By you can't have your cake and eat it, too. Maybe she is going through a crisis of faith though... Anyway, her freedom is actually in her own hands.She doesn't need to harass her husband to give her her get, she can just be free.
