i agree with "slowburn" -- rehab is not only so much more than the initial detox phase, but they are really two totally different pieces in the recovery process. there is just so, so much to be tackled, learned, and he will need a lot of stuff in his "toolbox" so that when life gets challenging, and when he is fighting cravings, he cal pull one out. the cravings can show up months, or even years from now - it is fairly complex. i think going to counseling is right now the very best decision for you. try not to project too much in the future - i know the fears and the questions and how they follow you around! but if he does an inpatient or an outpatient program, there should be a component for you, the fiance. part of it might be where he shares signs of relapse with you, what you would notice and how he feels (today) you should react.
