Which one would you pick? Committed friends or a committed relationship?

For the rest, what we commonly call friends and friendships, are nothing but acquaintance and familiarities, either occasionally contracted, or upon some design, by means of which there happens some little intercourse betwixt our souls. But in the friendship I speak of, they mix and work themselves into one piece, with so universal a mixture, that there is no more sign of the seam by which they were first conjoined. If a man should importune me to give a reason why I loved him, I find it could no otherwise be expressed, than by making answer: because it was he, because it was I. There is, beyond all that I am able to say, I know not what inexplicable and fated power that brought on this union. We sought one another long before we met, and by the characters we heard of one another, which wrought upon our affections more than, in reason, mere reports should do; I think ‘twas by some secret appointment of heaven. We embraced in our names; and at our first meeting, which was accidentally at a great city entertainment, we found ourselves so mutually taken with one another, so acquainted, and so endeared betwixt ourselves, that from thenceforward nothing was so near to us as one another.
