I don't know what she is thinking. Only she knows. Mystery is good as long as you don't backslide and start a relationship talk or pressure her. She may ask you what you had to do when you left tonight. Be polite. Be nice. Don't overdo it here. Pick your spots. Let her come to you. It IS a good sign that she stopped by to leave your things after the game. Why did she have your things? Why didn't you take care of it yourself? (Just making sure you keep showing that you are taking care of yourself) My guess would be that she was curious.
You are on the right track here. Stay on this path. It is important that you let her come to you. She will. We have to get you ready when she brings up a "talk". It is good if she is wondering. We don't really know what she is thinking at this time. Let her think all she wants. Strong, confident, silent strength. Be happy, act happy, act mature and pursue your own interests.
Grip, stance and alignment.
It is what it is. Let her come to you. Don't ignore her, but don't pursue her or act needy or pressure in any way. She needs to FEEL that you are perfectly fine without her. Enjoy your time alone. Just think.. You can watch whatever you want on TV, you can play golf whenever you want, etc. Learn to appreciate your time alone and learn to enjoy it. You will be a much better partner when she comes back. You have taken off all the pressure. Great job.
