I do aim to help, however...
Both awake at same time, he commutes, gets back at six, dinner is ready for when he gets in. I get kids ready and off to school, then work until pick up, after school activities, snacks/play/make dinner. I do the food shop once a week on Mondays, picking up extra bits with DC as necessary.
Dh is overweight and has starting seeing a dietician, who has suggested changing dinners to be more healthy. Tbh, I didn't think they were that bad, but I've changed a few bits. We have takeaway once a week. DC don't like salads and stir fry stuff, so I'm a bit in the dark. I have asked him to tell me what to buy, but he hasn't yet. I don't want to be looking into diet stuff in my 'free time' when he's not bothering, nor do I want to make meals the DC won't eat. Shouldn't he be helping with that particular mental load? It may seem petty, but it's just another job on the list for someone else who CBA.
