Care for a Camel, Sailor?

I just finished Still Life with Woodpecker by Tom Robbins, and I can't decide if it is bitter or not. It is jaded in regard to politics, revolutions, rebellion, democracy, socialism, communism, and government. It admits, indeed, it proclaims, that it is almost impossible to "make love stay." On the other hand, it advocates listening to the tides and taking big risks and "barking at the moon." I might have to read it a few more times before I can say for sure. There is one particularly bitter passage which I would like to share:

It occurred to her that in every relationship in which she had participated, in every union older than a year that she'd observed, imbalance existed. Of a couple, one person invariably loved stronger than the other. It seemed a law of nature, a cruel law that led to tension and destruction. She was dismayed that a law so unfair, so miserable, prevailed, but since it did, since imbalance seemed inevitable, it must be easier, healthier, to be the lover who loved the least.

Certainly not a new perspective (see radio selection), but a poignant one, given that I have always been the lover who loved the most.
