DH forgets everything so the mental load falls to me. He'll say he'll take on more but experience says this is a stupid idea as he'll forget it all and we'll all suffer the consequences. I've tried diaries, 3 reminders per task (one of which is written), visual reminders, telling him how it makes me feel if he forgets his share of chores. This morning he forgot something which had a little visual warning sign I'd made on it. I know this sounds controlling and patronising on my part but I guess the alternative is to just do everything myself.
Again, I know that this is always said on here but I genuinely think he has ADHD. He is intelligent and functions well enough in a pretty well paid job. There are reasons our life is highly stressful, I'm trying not to be too "outing" here, but he is legitimately very tired (as am I).
DH is the love of my life. He's always been like this but I've really had enough of having to act like the manager of the household.
