I feel for you. You are damned if you do and damned if you don’t. Can you bear to do a text saying you will always be there for him when he’s ready and leave him to it? It will be hard, but what you are doing now is hard on you too. You are making yourself ill and whilst he is on the coke he’s not thinking of anyone else’s wellbeing. It’s a cruel way to treat people, but thats what coke does to you. He probably feels like you are harassing him all the time, we know this isn’t true as this is what we do when we care for our loved ones and want whats best for them. At the moment he feels like what he’s doing is best for him. It seems like your life is on hold until he comes to his senses. Keep strong we are with you.
