Sounds like a great night, and that your W is starting to have second thoughts, and may be testing the waters with you to see what your response is. It could be a double edged sword - maybe she fears loss of control because you've dropped the rope, or maybe she truly is seeing changes in you and that has started to change her heart.
My only advice would be to keep doing what you are doing, positive PMA guy when you see her tonight, let her engage you and don't pursue her. If she doesn't (which is likely, generally a draw back after an advance) just be the happy go lucky volleydog living in the moment enjoying your D's Tball game. Like coach said - Know that you are being watched.
