If you want the dog, I would not let this woman take her at all. Sounds like you are taking much better care of the dog and giving her a good home.
I think if you do tell her that she will have to pay you for all you have spent on the dog before you give her back the woman will probably change her mind. You will probably need to be blunt with the woman and ask her if she wants the dog back, otherwise if you let her take the dog for a "visit" she will just never return her.
Like others have said it is good that you have the emails saying she wants to give you the dog.
You might suggest that she just visit the dog at your house, that you are way to attached to the dog for her to take it.
