Dating, like faith, is an exercise in strategic uncertainty. Andre Comte-Sponville notes that it is precisely the experience of uncertainty that makes possible the euphoria of what we call falling in love. We go through intense questioning, wondering, hoping, and doubting. Does she really care? And when that is followed by evidence that she does care, we have an endorphin tidal wave. It is precisely this roller-coaster ride of the agony of uncertainty and the ecstasy of relief that gives the early stages of love their emotional TNT. It is also why, as love matures, as commitment becomes sure, the roller coaster must inevitably settle down.
[At this point] we all think we want certainty. But we don’t. What we really want is trust, wisely placed. Trust is better than certainty because it honors the freedom of persons and makes possible growth and intimacy that certainty alone could never produce. … I would rather trust, because when you trust someone, you give him or her a gift, and you enter into a kind of dance. When I trust, I take a risk. I choose to be vulnerable.
