You are doing the right thing in sitting on your hands. He's got to make these mistakes in order to learn and grow up. You can't fix everything for him. I know it's difficult to watch him make mistakes...but it's time to sit back and allow your man/child to learn on his own.
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.
