Lucy, That is up to you. Do you feel comfortable enough to be at home? If so, I would be there just in case he decides he wants to take some other things. You can always stay in the house while he's loading the mower. I usually suggest that the spouse be there to ensure that the items identified are the ones that the MLCer takes.
Again, it's your call.
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.
