I've had similar struggles with my DP - he does all the cooking currently as I can't (hopefully by the end of the year that'll change as I am having my kitchen adapted!)...
I cut out all the snacky shit - biscuits, crisps, pastries, cakes.
Breakfast is a protein works shake.
Lunch is crispbreads, cucumber/pepper/carrot sticks/tomatoes (a selection of not all of them every time) hummus or cottage cheese, sometimes a hard boiled egg.
Dinner is - generally sensible, ideally not mega carby, includes veg. So the last few days its been a salad, home-made dressing, quorn thing sliced up/halloumi - last night it was a 'burger'... flat mushroom griddled with halloumi, on a burger bun with the usual salad/relish etc - crinkle chips. Fruit for after.
This is working, my blood sugar is lower, insulin intake is lower, fluid retention improved, so going in the right direction... but...
He keeps offering all the shit I cut out. In the first few weeks he would bring home biscuits, cakes, crisps and put them down next to me.
Him: I got you this! big grin
Me: No thankyou I said I wasn't having that sort of stuff now.
Him: Aww, I was just being nice.
Me: Nice is not offering me things I am trying bloody hard not to have, is it?
Him: But you like it...
He has improved but honestly, subconciously, the idea that ill change, he does not like. He likes things to stay the same, change scares him.
He is still doing things like... twice as much food on the plate as I have asked for. Making a shake he's supposed to do half milk half water, i find he's doing it all milk without telling me. Butter on things that don't need it.
He brought home a HUGE packet of milk and honey shortbread biscuits the other day and presented them to me like the holy fucking grail!
Its all a very long winded way of saying 'i get it'...
It wouldn't matter what the food choices HE makes for me, were - the point is I've asked for something/to not do something, and he KEEPS trying to do the thing I've asked not to do.
That isn't ok. It wouldn't be ok if I'd decided to eat a cake and he was offering salad!
So its irrelevant that the high protein fried breakfast (or at least some of it!) was a better choice than high sugar/high carb bananas on toast.
He isn't listening and respecting your choices - he's trying to force his choices on you, and getting shirty when you advocate for yourself.
(But do look up the carbs/sugar and tweak it a bit, you may well find your sugar cravings drop a lot if you can balance that out and avoid BG swings!)
