Recovering food addict here as well. I gained all my weight through yo-yo diets and binging. "I need to do it." "I just need to stay strong." I can tell you from experience, this is not the right attitude to have. Part of loving your body is learning to listen to it. Trying to win against your body and beat it into submission can feel like beating your head against a brick wall. Even when you master it for a while, it only takes one slip to send you back to the beginning. You can't expect yourself to be 100% strong all the time. Sometimes you'll be tired or sad or lonely or stressed or upset, and that's when you'll walk into your house and be sideswiped by an amazing smell and you'll slip up. It's not your fault, it's how your body is. Being in a vicious cycle like this, it's tempting to think that with luck and timing, you'll brute force your way out and be free. The truth is that there's no strategy that will make your willpower impervious 100% of the time, forever.

Your body is designed to be healthy. When you get that crazy FOOOOOOOD I NEEEEED IT voice, thank your body because it's telling you something important. Loudly. It's not getting what it needs to be in balance. When you cheat on your diet, it's because your body needed something it wasn't getting. Keto is all about using the body's natural processes to switch fuel sources. So when you have a massive craving that can't be satisfied by fat it means your body still needs carbs, and it's not getting them. It's the need itself that you need to address. It's probably that you're eating to many carbs for your body to get what's up and start doing the ketosis thing, or else that you ARE burning fat, but you need way more. Or maybe it's just too soon and you need a day before you can relent with the self-denial.

Tempting food will always be there whether your wife brings it to your house or not. The goal should be to deal with your cravings, the root of the problem, instead of just the surface problem of the food. So like for example, wife brings home pizza, your brain starts going I want it I want it I want it I want it, you say "thanks body!" and eat all the cheezy yummy toppings off of your poor wife's pizza, chug some water to help you feel full, take one teensy pinch of that stupid crust just so you can stop thinking about that freaking flavour, and be all happy.

I admit transitioning into keto is brutal and you have to deny yourself. Maybe you should explain to your wife that you need a temporary break from the food in the house? That might be easier for her in practice if it's not forever. Go like one or two weeks. That should give you time to adapt to the point where you can satisfy yourself with fat. If that just doesn't fly with her, don't worry it's not impossible!! I live in a family with 7 children who are constantly cooking, baking, with no hope to stop. While it would be nice to pit my laziness against my gluttony and let them just fight it out, it's not totally necessary. Maybe a solution could be to go away from home for a couple days? You could get a hotel room with no kitchen and declare it a food free zone, then if your wife wants to cook she can just pop back to your house for a while.
