all IsDaveThere My frustration is I do all the grocery shopping so it’s always me having to pop in the shops for him. I do the bulk of the cleaning so it’s really easy for DH to add a small cleaning task.
I left an ex after 30 years with him, and this was no small part of why.
He was amazing at trying to avoid his fair share of chores. After we'd had the DC, I went part time, but that was still 28 hours a week compared to his 39 hours. Yet he'd still expect me to be the one picking up every household/child related task while he sat on his arse. He'd wait until I'd pretty much completed everything before asking "is there anything I can do?", late in the evening.
When I finally went back full time, he was asking me to do x, y and z until I pointed out that actually he was the one working slightly less than me. Surprise Pikachu face time, he clearly hadn't expected me to pull him up on it.
I told him he had to do more. His main days off were in the week so I told him he could do the cooking, as well as chores, on those days. I only found out, after the DC and I had left, that he had dumped the chores on our DC, expecting them to do them after school and in preference to completing their homework. They'd been too scared of him to tell me. I didn't realise, as he had done dinner on those days.
So @Londonlassy if you don't want this to fester with you, you need to be pulling him up and asking him to do his fair share now. OK, you can do a little more, because of your slightly fewer hours, but he needs to be taking a fair share of anything over those few hours.
