Romantic love isn’t so much a single emotion as a container for many shades of emotion. That’s why we’re more susceptible to feeling hurt by a romantic partner than a friend. That’s why we can be infuriated with a lover and long for them at the same time.
Some loves have a way of containing the vicissitudes of romantic relationship while remaining beyond them. Underneath the range of emotions that play through the heart, lighting it up or ripping it up, there is a quality of love that witnesses. In a way its not so much a quality of the heart but a quality of Being.
Rare to experience in romance, but exquisite when its there.
