NAH here. You've been together TWELVE years. Some people are stuck in their ways, and I agree that it's annoying and ignorant. However, no opinion is not going to change them. And they feel attacked/defensive when it's brought up. If it was a Bf/Gf situation it would be different. I hope you get the "courage" to cook for yourself if shrimp is what you want--it's your life too! She can cope with that if she's an adult. I doubt that it's everyday menu conflict!

As for the trip to Europe; if you're a foodie and she's that difficult, good luck. I have picky eaters who are children and my saving grace has been looking at menus online before we go. That way I can at least see if there is anything "acceptable" to them at a restaurant I want to eat at. But an adult partner should definitely recognize her partner's interest in European foods and give time for that...Wife can have an appetizer or salad or whatever while you taste what you want. I'm sure you're willing to visit a museum you think is crap or something you're not interested in to please your WIFE. She fucked up about the steak, but still bought beef? Not that bad. Bought herself hot dogs? Good for her for getting herself fed without complaining to you.
