Another thing - now when the court didn't give her what she wanted, perhaps she will change her mind down the road. If it were me, I would give her time to think about her situation, feel what it's like to live like this, struggle with the distance, and then you can reevaluate in a year if she has not changed. I have a feeling you will not be so eager to move then, but who knows.
If you intervene now, I think you'll take away her opportunity to develop. Does that make sense?
