ADHD and Marriage or adhdmarriage(dotcom)-This has been incredibly helpful. And it's not just for married couples. Any adult with add/adhd can benefit.
ADDitude or additudemag(dotcom)
And the only quality support group for adults with adhd in my area is The Manhattan Adult ADD Support Group. maaddsg(dotorg) I only wish they met weekly! Very informative and positive.
I hope this is helpful to someone out there. :-)
