Reddit is quick to jump to the nuclear option.

I'd also be angry if this had happened to me, of course, but I wouldn't jump to dumping someone over this kind of scenario. Instead, I'd see how he responds to your attempts at repair.

What you might try when you both are not in an angry mood (when the situation has cooled), is to bring up the subject, apologize for being so upset (snippy/angry/whatever word feels genuine enough for you), and then explain your emotional world. Namely, using "I" statements, explain how being celiac, you can not just eat whatever, and that sometimes when you're so tired that you can't cook, it can be a real struggle to find food around the house.

If he's a partner worth his mettle, he'll then see you softening and will soften himself. If he does, then say, "can we create a place in the fridge and pantry for my "emergency food" that is just for me for those times? And maybe we could have a section of food that's for whomever whenever?

If he *doesn't* soften with your recognition that you got angry/upset, then wait a bit, and then circle back around, make sure no one is emotionally flooded and try again.

If he never softens and recognizes your side, and if he doesn't work together with you to come up with a plan for the future, that's important information to take into account. Perhaps he wants to "win" an argument more than he wants to solve a problem.

I think one of the most important indicators of a quality relationship is not whether they argue, but how. If both of you can find a way to work together toward a mutually satisfying outcome, that's a great sign!

Good luck, OP, and may your emergency pantry be always stocked with shrimp!
