Honestly there is no right track. But you guys do seem to have your shit together. I really don't have anything to say, but welcome to non-monogamy and keeping being open and honest.
My only ... warning would be you add a lot of complexity to finding someone special when you make it a couple vs 1 person. My wife and I start as Jenny block did. We hunted unicorns and in the scheme of things were pretty successful. About 10 months ago we decided to split our desires and start looking for people we could love as individuals.
