Gosh. This is a tough one because of course you are worried. However, surely if something bad had happened his parents would have contacted you, you know? Would his parents tell you if he was using and had disappeared? I hope he's not on his way back down to bother you again? Looks like I'm not really helping....I'm sorry! I can say for sure that hearing about your family being supportive is wonderful news! That is a great relief to you I am sure! Just know we care and are supportive of you whatever you decide to do!
