Has he ever been on a programme before ? Only you know if your truely ready to move on without him. Ask yourself this if he did get clean and he remained clean would that be all you wished for in life because there is a chance. If he gets on the programme and is successful would you then kick yourself for giving up when you did. You can try and turn your love into hate i tried but i found its almost like your lyeing to yourself which still makes you misrable. You say youve got to the stage where you dont care anymore if this is true and you can walk away then by all means do it. However your next sentance is about the drug tests suggesting you do care :-/. I know its like living in a nightmare. Why dont you talk to him say you love him but you cant take it anymore tell him you want this programme to work so bad and if it does you will continue your relationship with him if it doesnt that is the end. In the meantime have as little contact as possible. If he calls you wanting money say no these are not the calls im interested in anymore by all means call me and tell me your clean otherwise dont contact me. Tough love is needed. Try not to drown yourself in his addiction that way if he sinks you wont be at the bottom with him if he swims then he will be right there with you x
