It may be different in your part of the world, but I remember when we attended family rehab, it was all about the recovering addict and how they feel. And how they feel they are progressing...
No deep subject when we attended.
May be different in your case, let us know, okay?
hugs and hugs.........
P.S. You mentioned you don't much remember the bad times. Well if your addict actively seeked out recovery...then why dwell on those issues at this time anyway?
Maybe it's a good thing to remember the good times, and know how it CAN be....with a lot of hard work and dedication to maintaining sobriety.
