Tam, I can understand your worry, and that shows me that your a loving and caring person. You two are no longer together and your worrying if he is alright, and if he isn't your sad that he's alone. A therapist once told me when I was in panic mode over my addict son, to envision my son with his guardian angel right there to help him. And to get rid of the vision of him dying or overdosing. Picture those angel wings wrapped all around him. No matter what happens, your powerless. At least you know your a loving caring person. Is there any other way to find out what's going on with him without contacting him? You sound really worried, and you need to ease your mind without creating drama.
