When it comes to the money, well, she can wish for whatever she wants. Wishing, however, isn't reality. You need to sit down and calculate out what the separation will look like and then apply some reality to your daughter's plans. Reality bites. Wishing that your rifle still works after it's dropped in the sand isn't the same as making sure it does. Get it done.
On another note, glad you're working hard and that you've got things to do. Lot's of others don't have that and wallow. With everyone responsible under you make sure that you keep your life balanced. Work, money, life.
