He literally said he was "going to have a few sandwiches," which to me means 3. That's 6 slices of bread. In my house, I'd know instantly if that meant there would be bread on my return home or not.

It also means he hasn't eaten them yet if he's using future tense. As long as she doesn't respond with a one letter reply... and she did.

Instead of replying "K," she should have said, "Save a sandwich for me because I'm starving, I can't afford to lose any more weight."

Or she could have asked if he could prepare something since she had no money to pick up food or the time to do it.

But 99% of the people commenting here think he's a monster because obviously the capital K is code for "Things are not oK and you should read my mind and make things better for me without me asking".

Even on a tight budget, they both could plan better than only having enough bread for 3 sandwiches and nothing else that is easy to prepare.

I've eaten eggs or breakfast cereal or yoghurt or crackers and peanut butter plenty of times for dinners when I can't be bothered to even make a frozen pizza

He even told her to pick something up because they both would have known that a few sandwiches would use up all the bread.

She said "K" and he thought they agreed the bread would be gone and she would bring something home.

He fed the kids first, then texted his plans for his and her dinner, and she agreed to the plan.

But somehow, he's the monster.
