You did really well in that conversation. You and your wife would benefit greatly from a Retrouvaille weekend. As you know, this phase of marriage where things are boring and one spouse starts looking for the brass ring is very common. Retrouvaille teaches you how to move on to a much better relationship.
It is not therapy. It is learning how to communicate with each other. They teach a skill and give you time to practice that skill over the weekend. Once the communication within the marriage is fixed, in most cases, the marriage improves tremendously. And that leads to happy people.
The website has more info, http://www.helpourmarriage.com. You can read on Limbo and EdieMaire's threads how it worked for them. Both went just 2 weeks ago. I know a lot of places have weekends coming up in October. It is actually a very nice way to spend time with your spouse.
