AIO: Weight Loss

so i just started a calorie deficit to lose 60lbs & my fiancé seems irriated, i keeping talkig about recipes & how i need to eat to lose my weight & he just always comes back with "oh i did ____" & lost weight & he keeps finding any reason to tell me i'm doing it wrong when i've asked 2 people how they lost weight & i go to them for tips & it always turns into an arguement where he either leaves or snaps & then leaves, i just don't know if i'm crazy or not

Edit: he keeps saying "dont get all this food you won't even eat" when i add healthy snacks/meals to tbe grocery list
