If she shows up, be gracious and treat her just as you would your other guests. This will be the time to put on your best behavior as an actor for she will definitely be observing how you are around her and others.
I suggest that you get some nice smelling air fresheners and place them around your home. You want her to leave w/the reminder of how nice your home smells. I would also have some goodies there for your guests, i.e., cookies, etc. You don't have to get elaborate stuff, but have some nice nibbles. Again, this is the time to shine!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
