Wow. This is the other side of the coin for when my T says he says he can be my therapist or he can be my friend, but he can't be both. You are trying to act as a therapist to your friend. According to the "rules", you can't be both? This is more like codependence what you're doing, being in a relationship with someone who has an addiction and you want to fix them. If you can do "friend" things together that make both your lives better, that would be great. Otherwise you may become two partner addicts, pulling each other down, each getting involved for their own reasons, their own pain, their own unresolved issues or whatever. Like an alcoholic married couple. Hmm. What are your parents like?
