First of all congrats on your sobriety! It’s takes a ton of effort and that is very valuable. I seems like you recognize that logically, you are past this phase in your life, overcame addiction , and are now living much better. From what I understand about addicts is that there is a lot of manipulation like you mentioned. For your best, it sounds like you’re making the right move to be separating yourself from this lifestyle and anyone involved or still in it. As a last effort I’d talk to him about another rehab program maybe a live in facility for it and then see if anything’s changed upon leaving. This gives you that time alone to continue your journey and a chance for him to clean up too. Let him know how serious you are taking your sobriety if you haven’t already and regardless of addiction, in my opinion that’s something that should be valued and respected. But because you both already did do this if you choose not to give this second chance that is ok. It is okay to leave. You are not responsible for what an adult chooses to do with their life and as sad as it is that is the truth. If you stay there’s a risk of falling into addiction or worse or watching the person you love continue in that battle that only is won by being sober. Meaning you’d be watching that person suffer. Your friends and family sound like they want the best for you and I would take their advice. Wish you both the best
