If you remove the “I paid for this food” factor, and just leave it at “I made this food”, the response you’re describing here fits the stereotypical Jewish/Italian mother to a T. “Eat! Eat!” she implores. “Why won’t you eat? I cooked this just for you!” She hovers, distraught. So you eat, to please her. And yep, this leads not just to eating disorders in later life, but to a whole host of neuroses and issues, not necessily food-related, rooted in the fact that in order to please your mother, you must eat (read: accept) what she has passively-aggressively forced upon you. It’s a control issue.
Don’t wanna turn this into a flaming, bitchy “get help!” thread, but seriously, dude, hear some totally unbiassed opinion: you’ve got some issues going on here. If this girl is The One, I’d strongly suggest the two of you get some kind of premarital counseling before you tie the knot, because as it stands, IMO you’re a divorce statistic waiting to happen. Your need for control will branch out into other areas of her life, and your nascent feelings of martyrdom will, too, and before you know it, she’ll be packing her bags with quiet determination, saying, “I just can’t live with you anymore…” And you’ll be standing there, baffled, begging her to explain why.
Stereotypical Jewish/Italian controlling mothers can’t understand why their children need to move out, either, or why they never call, they never write…
Why should your feelings be hurt when she doesn’t eat your dinner? It’s just food. You’re a team; one team member fixed food for the team. If it doesn’t get eaten with a lot of Ooohs and Aaahs over it, you don’t have the right to be personally offended, because cooking a meal is not an opportunity for personal validation–it’s just food. Somebody has to go out and slay the mammoth for dinner; so when you bring home the big chunks of meat over your shoulder, she’s out gathering nuts and berries, and isn’t there to Oooh and Aaaah over your cavemanly providing, so big whoop. Just because your Dad demanded lots of approval and validation from his family for bringing home the mammoth doesn’t mean that you need to, too, especially because this girl is just your live-in. She’s not your wife, she’s got no personal stake in you, so she doesn’t have to pump up your ego every night at supper in order to keep you slaving away at McJob so her children can be fed.
My husband carried mail so I could be a SAHM. We never felt a need to pump up his ego every night at dinner. We all knew he was a good provider, and he was content to know that we knew. He didn’t feel a need to bang us over the head with it every night. Guys who do that are guys who aren’t very secure in what they do, so they need to have external validation.
So there’s other stuff going on here besides just “she won’t eat her supper!”. Try not sulking when your GF doesn’t eat her dinner (oh, and here’s a hint-- “Freezer”. Stick her uneaten dinner in a tupperware or a baggie and shove it in the freezer, it’ll be fine, and do it without an air of martyrdom, me boyo, simply with an air of cheerful matter-of-fact practicality, “don’t want to see this go to waste”), and see if other aspects of your relationship don’t perk up. Try it for a month.
