The above is what DH has started saying to me any time he wants me to help with DSC. Aibu to want to punch him whenever he does.
We share a young child and for my own sake, I have had to take a big step back from how much I do for DSC. I realised I was being expected to do way too much.
DH has noticed and he makes little digs from time to time. And if he ever wants to guilt trip me into doing something like picking them up from a hobby because he's late at work or sort their birthday presents because he's "not sure how to work the website" then I get "just imagine you're doing it for X if it helps" X being the name of our shared child.
It gets right under my skin.
