But op, you ate the pizza. You did benefit from it. And your child wasn’t rude and didn’t disrespect you, she’s only 5. She’s just a little girl who was excited to get pizza and saw you ruining her treat and arguing with her dad over pizza. She’s 5. The thought process goes no deeper. Her brain doesn’t work that way, but you’re so hung up on being disrespected, When it’s just you don’t get your own way,
The only person who undermined you was you when you started eating the pizza. Your argument would stand about being so full or not benefiting if you didn’t eat it. But you did. so buying it tonight or tomorrow made no difference. All three of you ate the pizza. So you all benefited from it. It’s the same price either way.
and if money is so tight you can’t afford pizza, then why are you now saying you want to buy something nice for you to eat when your husband is out tomorrow, when you had dinner, then you ate the pizza.
If money is that tight, then sit down and talk, look for other solutions, for example possibly returning to work full time now she’s in school, because buying it and eating it on a sat v a Friday won’t save anything. Buying even more for yourself tomorrow will cost more.
i don’t know what else is going on in your marriage to make you behave like this, I’m guessing it’s very bad and one of you will call the end soon, but i do know this was a pointless and petty argument that in this instance you caused.
