I need to know how to cope with an drug addiction partner. My fiance has a drug addict. He's been to many rehab center. Unfortunately this didnt help. He have told me so many lies about kicking his drug habits. I have been giving him some suggestion on getting help. He stated that he will. I never so him call no one or visit any treatment center. He always tell me I never been on drugs nor did alcohol. How can I help him. I told him by start I will support him on getting help. He use so many excuse for stopping. It gotten so mad that he stay out all night, don't call for days, and when he do call he thinks that everything ok. Need Help.
