Use this time to look after yourself. You need to leave him to do whatever it is he feels he needs to do. Cocaine causes major disruptions in brain chemistry, extreme highs but also extreme lows. He may be feeling guilty and disappointment in himself. Find a local group for families of addicts and go. More insight is key and you can learn how to help in the best way. Lool for support for him so you can suggest it to him, she’s him a contact number or day/time/place so he has the choice to go if he really wants help. That’s all you can do. I’m so sorry you are going through this. Hope you have someone to talk to. I’ll be around on here for the foreseeable as my partner is addicted to crack cocaine and I’m in same boat as you.
