Im more into history,museums hole in the wall bars and food while she likes the usual shop for way overpriced items.
Denver area has all of that. Several good micro breweries and bars, lots of unique dining options, and plenty of uppity/artsy shops for her to waste money. Plus it's beautiful, if you've never been. I've only spent a few days there, so I wasn't able to hunt down anything historic as far as old war memorials, museums, etc, but I checked out Pike's Peak, Garden of the Gods, and a couple of other places in the vicinity. Not sure what the situation is up there with the recent fires, but that's my suggestion for a week long spot within driving range.
