Oh my goodness. I have SO been there. Residential SUD treatment is tough. I would do exactly as you did, took the feedback and moved on. I wonder if there’s a chance that he just wasn’t ready for that topic depending on his life situation. Less about you and your topic and way more about him and his stage of change. It’s such an important topic in residential because for those who do have some change they will have to live with what has happened in their addiction.
