Group sessions

Anyone here participated in group sessions with other ADHD couples? Our counselor is really interested in starting a group for a few couples she has all dealing with ADHD issues, including us of course, and I am wondering if anyone can weigh in on the pros and cons. I was discussing with her some defensivness issues that are coming to the surface for my if he wants to embrace the ADHD diagnosis only when it explains why he has felt different all of his life, but is not so openly accepting of the communication difficulties it causes us (it is all my fault when a conversation goes south..when he TRULY mis-interprets something I say..and I am left holding the bag unfairly, I feel) She said that the group will help reduce the defensiveness and help take the heat off of each individual and let us all see the issues in each other..even the non-ADHDers. Anyone?
