That's the question Chapman is trying to help us answer. How do we keep feeling the joy and love and fulfillment we need when we're doing laundry together and watching each other be sick? How do we stay together?

Overall, I think the information is useful. Everyone's answer is going to be a bit different, and this book offers a road map for at least getting to the right general area. And it boils down to this: Do the work to know yourself and the person (or people) you love.

The one minor irritation, for me, was the author's perspective. He comes at relationship from a Monogamous, Christian point of view. That doesn't invalidate the advice contained within. But it does inform some of his anecdotes and examples enough to be a little tedious if that's not where you're starting from.
