I might like to warn you, something I find comes up with my partner is that because he doesn't get it, the disorganization, I mean.
He thinks he is helping by offering advice or solutions, when all that really does is make me feel like a child.
Patronized and made to feel somehow inadequate.

I am a grown woman, nearly 40 and have raised 4 kids.
My eldest is in Uni.
And I managed this with chronic MI and a 24 year drug addiction.
Whilst my way isn't his way, I am still capable.

Just be careful not to fall into that trap.
Of either doing everything so it gets done to your specifications, then commenting they don't help.(it can make your other feel utterly worthless.)
Or pushing advice if it's not asked for. (Resulting in feeling like your telling your other what to do. That their efforts aren't worthwhile.)
Aside from that it sounds like you have a good grasp of what's happening.
So once again, all the best. And good luck.
