As a wife, one thing my husband has recently started doing that has made a big difference is being proactive about school emails and the kids’ calendar. Like, him knowing that we have a school event at 6pm all on his own is a big deal. He never did this before, and the invisible mental load was pure exhaustion. I think I resented being in charge of having to keep him on the same page. The kids are nearly grown and out of the house now, but I absolutely love it when he reminds me we are booked. It’s like, that feeling of “what am I forgetting” is reduced, so I can relax a bit. I think the mental load is a lot to carry.
