Ah yes, mental load. I know it well. The resources look great!
I've explained this concept to my partner, who shares equally in the doing, but isn't so great at the thinking/planning/organising/prioritising that facilitates the doing. Part of this is due to his dyslexia and ADHD, but he's also... a man. With his neurodivergence in the mix, there's not a lot we can do to seriously address the mental load I carry, except to continue to communicate and work together on how he can redress the balance. Mostly we're okay at it, and when we're not I get to have a good loud moan and he listens and acknowledges what I do for the family in this respect. That goes a long way, and like PP have said, tech helps. And I will say that my partner, being a far more securely attached, patient, positive and calm person than I am in general, pulls a lot of weight when it comes to emotional stability. I try to remember that when I'm feeling the pressure, and it's something I need to work on helping him with in return. He's the smiling rock. I'm the worrier/overthinker. Both of those traits feel a bit necessary for our family to work.
Also, @MagicPortalToMarriage if you don't understand the concept of mental load, I'm not sure why you're weighing in? The point is, if someone (usually a woman) doesn't do that thinking, then all sorts of things just don't happen, or they go wrong in such a way as to have a negative impact, such as making even more work, taking more time, causing distress that could've all been prevented. Then someone (usually a woman) has to go out of their way to mop up all of that consequence. Once upon a time, we only had to think for ourselves (note for not about), then we acquired partners who expect us to think for everyone. It's fundamentally unfair. They have brains too. Why should our brains pay this tax, when theirs don't have to? When they have all those minutes free in the day to just... daydream? Think about what pleases them? And, it's relaxing to have that freedom, which helps to bolster their mental health and wellbeing, while those carrying the mental load on their behalf suffer the loss of their headspace in real ways - tiredness, worry, anxiety, depression. It's like having a job, except the expectation is that you don't clock out. Carrying the mental load is real work. It's just unseen and unpaid.
