@Deedee121
The responses you've had here are just really disappointing.
You've posted for support with a problem as you see it, from people in the same position, and a bunch of other people wade in trying to police how you should present your problem.
It's a crazy situation where someone reaches out for support and the response is to take offence, or demand that a different focus is taken.
I work in Mental Health, I understand ADHD pretty well, and I also have a husband and two children with ADHD. I do my absolute best to advocate for people with ADHD. But I'm also a wife. And it's really fucking hard sometimes. Of course, not all the problems are ADHD (thanks to everyone who has pointed out that some husbands can just be arseholes, yeah I'm sure @Deedee121 hadn't worked that out...) but I'm guessing that through your child and DH you know ADHD pretty well and have a fair idea what problems are ADHD related and felt that some peer support with that would be good. ADHD can undoubtedly end marriages.
In this kind of situation I think facebook groups work best. Clearly titled with questions and controls over joining. Rather than this format where a bunch of folk (who aren't really the target audience) get exercised by the title and wade in to kick someone while they are down. It's the equivalent of wandering past a church hall running a support group and storming in because you have some vaguely related issue, knowledge or experience.
If only people could read the title and think "nope, doesn't apply to me" and move on, rather than storming the hall. Or start a different thread if it triggers some issue for them.
I'd love to tell you the long list of ADHD issues we try to manage in our marriage and give you a bit of solidarity and mutual support but there are people here who have actively obstructed this thread becoming a suitable space for that.
