Maria Popova writes on Rainer Maria Rilke and the contrasting pulls “of autonomy and togetherness” that characterize so many healthy relationships. Rilke writes to a young correspondent:

I hold this to be the highest task of a bond between two people: that each should stand guard over the solitude of the other. For, if it lies in the nature of indifference and of the crowd to recognize no solitude, then love and friendship are there for the purpose of continually providing the opportunity for solitude. And only those are the true sharings which rhythmically interrupt periods of deep isolation.

And Rilke writes elsewhere on healthy togetherness and boundaries, where he movingly expands on the idea of our “willing to stand guard over the solitude” of the other, and in so doing balance between the two poles of love, autonomy and forfeiture.

It is a question in marriage, to my feeling, not of creating a quick community of spirit by tearing down and destroying all boundaries, but rather a good marriage is that in which each appoints the other guardian of his solitude, and shows him this confidence, the greatest in his power to bestow. A togetherness between two people is an impossibility, and where it seems, nevertheless, to exist, it is a narrowing, a reciprocal agreement which robs either one party or both of his fullest freedom and development. But, once the realization is accepted that even between the closest human beings infinite distances continue to exist, a wonderful living side by side can grow up, if they succeed in loving the distance between them which makes it possible for each to see the other whole and against a wide sky!

Therefore this too must be the standard for rejection or choice: whether one is willing to stand guard over the solitude of a person and whether one is inclined to set this same person at the gate of one’s own solitude, of which he learns only through that which steps, festively clothed, out of the great darkness.

And on properly giving of oneself, and on having a self to give:

All companionship can consist only in the strengthening of two neighboring solitudes, whereas everything that one is wont to call giving oneself is by nature harmful to companionship: for when a person abandons himself, he is no longer anything, and when two people both give themselves up in order to come close to each other, there is no longer any ground beneath them and their being together is a continual falling… Once there is disunity between them, the confusion grows with every day; neither of the two has anything unbroken, pure, and unspoiled about him any longer… They who wanted to do each other good are now handling one another in an imperious and intolerant manner, and in the struggle somehow to get out of their untenable and unbearable state of confusion, they commit the greatest fault that can happen to human relationships: they become impatient. …

We’re think of ourselves as romantics, but we seem to know little about love.
