The honeymoon phase is special in that it brings together the relief of reciprocated love with the excitement of a future still to be created. What we often don't realize is that the exuberance of the beginning is fueled by its undercurrent of uncertainty. We set out to make love more secure and dependable, but in the process, inevitably we dial down its intensity. On the path of commitment, we happily trade a little passion for a bit more certainty, some excitement for some stability.
