I experience romantic longing as a warmth starting in my heart which radiates outwards depending on intensity. Normally it only gets to about my upper lungs, but sometimes it makes it through my torso and a little bit down the upper parts of my arms. It feels slightly pressurized, but is incredibly pleasant.

Connectedness feels similar to that, but cold and associated with blue, with weird sensations in which my head either feels floating, or my arms don't feel separate from the world. This is a very rare feeling to have much of, normally when it happens it only occupies a section of my heart.
