Bright, Go to your vacation home and enjoy your peace and quiet. The number one priority is taking care of your. I know you want to rescue him, but you can't rescue everyone...your BIL will be fine. I'm sure he'll hook up w/some friends and do something that day.
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.
