it's totally passive-aggressive.....and also plays the "read my mind and know what i really want" card. i wouldn't call it codependency, per se. i'd call it setting the other guy up for failure, which will then justify a full on snit. another resentment to add to the collection.
it also could be that the woman thinks it would be poor form to ASK for something calorie laden/fattening like ice cream, for fear of looking like a glutton or someone who doesn't care about their appearance?
