Karried you are a good person, mom, and friend. You did the right thing. The hardest lesson to learn is that we as concerned friends and parents have to learn to let go and let live. You can be concerned, but you can't own their problems. It's their responsibility as his parent to deal with these issues, not yours. So don't lose sleep - you can be there for them when things happen and you can give advice when it's asked for, but you have to let them learn on their own. It is their mistake to make.
