I am still remembering how he told you that he had run away to San Diego or something and was never coming back. That he was going to live on the lam forever.
He needs to at some point understand in a real way what the consequences are of his choices and his attitudes. After this, if he keeps messing up, he seems to be determined to do so.
I am getting in a very real way that my son's life and my own are completely different. No longer connected as they once were. I have my own life. He has his. I love him as much as ever, but I am not responsible.
