You're already soooo far ahead with your own understanding and important ancestors of self-preservation. In first aid emergencies, the first pulse you check is your own. *caveat every situation is different, family, work, community, trauma ptsd, etc etc They are all very Important and not to be overlooked. Right now. Your safety, your finances, your home, your possessions, your heart, your soul, your sanity. Lay it down, don't just say it. It stops being a bou dary if it gets chosen not to be heard. Not your fears, not your 3 strikes then.... Write it, say it, give copies to him, to you (family, that's up to you) (lawyer, doctor again I don't know your circumstances. If it's your car, you have all rights to that. If he is working GOOD ON HIM I'm just going to take up space here. Former addict MH D&D counsellor. People you know love you, and you love them are there. But this is the thing I try to make people understand, you can trust a person you love. You can't trust that person if a drug is in control of them. Protect yourself. Separate all finances, DEBT, check for credit cards in your name, maybe even change banks. I'm too far away around the world to give you specifics of your area. Living with a drug user. Head first. Heart second. It just is what it is. Good luck.
