When my son was in rehab the first time; we were advised by the director that it was very important for us to take step back and to allow him the space he needed to do the work of recovery. It was not directed _at_ us as parents; but instead _for_ his benefit.
I viewed this time of detachment as an opportunity for my son learn how to do what it takes to save his life. Recovery is serious business and for many requires placing the focus _only_ on getting well without outside entanglements.
