Now, here's the flip side of the coin: You need to stop imposing your ideas of what you think is needed for their ideal RPG to be any good. If all they're looking for is a series of combats they can win and move on to the next, then that is all you need to give them. And be THANKFUL that you have players who are willing to show up regularly regardless if they are getting exactly what they want, or what you want. Because a lot of times, compromise is what it takes to keep a group playing together despite differences. And the fact that everyone sat through 8 supposedly unsatisfying months of a 4e campaign shows you have a stable group that includes your spouse! Do you know how many people out here have only ever dreamed of having such a gaming circle available to them?
Now, I don't recall all the details of your last raving regarding what happened in your 4e game. It seemed everyone was mostly ok with the parts that appealed to them the most (i.e. fighting monsters, kicking butt, and taking loot), and less thrilled about the parts that you insisted were the best parts of the system (i.e. skill challenges, etc) even though they clearly did not care/ask for those bits.
I get not being able to run the games you want the way you want, but in this case, you're being asked to do less and focus on only parts of the game that appeal to your players. They don't want to give you a wish list for magic items? So what! It's not a requirement. Pick out the items for them, or roll random. In fact, strip it down to Essentials only so there's four books you need, and run Encounters for them. Use the Chaos Scar for a bare-bones setting and a dungeon-of-the-week style game. 4e is literally the easiest D&D system for DMs to throw stuff together that will balance and entertain players for a few hours a night.
You're just as hung up on your own ideas and expectations as your players. That is largely why you've been suffering with this for so long. I'm surprised your group is still trying at this point, but I suspect there is more to your group than playing styles and preferences. Honestly, it is that relationship and bond with these people that matter most. Take care.
