Its exactly same what ive been doing. Im not defending him, but it is hard and i have not had it since new year. Big thing is hes admitted it now. He needs to learn about emotion, and mental and physical relapse now. To avoid it.. and make him watch the 1st part of louise clarke on cocaine on you tube. He will realise then hes an addict. If you need any help just ask ive learned a lot how to quit.. its just sticking to it.. and my opinion your doing right thing staying and helping him out.. if my gf kicked ne out now, id get a flat, i work hard aswell, and ill be getting coke every weekend. Then coming down on my own in flat all by myself. God know what id do. Am so gratefull my gf helps me. Just be on his case and keep telling him be positive.. theres an app called pocket rehab.. its were people have all sorts of addictions and its like a chat room and you all help each other out its great.and tell him dont be ashamed of downloading it. Up 2 u tho.
