Have guests staying, where one has IBS and is on the fodmap diet: gluten free, no garlic, onions, lactose etc. I didn't know how restrictive it was until they turned up so my meal plan for cooking for them has gone out the window. We're veggie with small kids so it's incredibly difficult to find meals that work for everyone.
AIBU to find it annoying that he insists on this diet when he's eating at home with us and I'm preparing meals, but then eats croissants and onions and lactose etc when he's out (and there are fodmap friendly options), then merrily complains that he'll 'be paying for it later'? He has also bought and eats lots of biscuits (which clearly aren't gluten free) but won't touch any of my cooking if there's gluten/fodmaps in it. And I'm not a bad cook!
I've suggested that we cook some meals together (they're staying for a month) but that they sort most of their meals out and cook meat if they like. I feel like a terrible host as I love cooking for people, and I clearly don't understand IBS very well. In my mind surely you eat something or you don't?
