Question's I would ask Dave if I could somehow communicate with him.

Where is your wedding ring?
Do you want me to re-marry or not?
If so, will you help me find a good man?
Have you been through the repentance process and have you been forgiven?
Is our temple sealed marriage still intact?
Do you still want me to be with you forever?
What was the purpose of the car accident last April and did you orchestrate it?
Do you come and check up on me every night between 2:00 and 3:00 am?
Do you still love me?
Do you remember my secret pass word?
Is there any important messages you can tell me or warn me about?
