Your son is old enough to have a conversation w/your h. I have to agree w/Andabelle....he should be contacting buddy to ask him if he had fun. He not only pisses me off, but I could take a couple of swings at his head with a baseball bat.
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.
