I wouldn't worry about telling her your decision at the moment, she doesn't really have the right to know. I think your telling her you are going to move through this together as parents probably covered it, but not too much...still some ambiguity in there... Let her think what she will.
She hasn't moved out, she isn't sure what she wants, so you still get to show her the new, improved PW...
