If you stay, then find something to do in another part of the home or in the yard. You do not need to stay in the area that she is packing. Be civil, but don't be overly friendly. Stay calm and if she talks to you, look her in the eyes and keep your voice level and calm.
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.
