This post is dedicated to the reverse romantic. The incorrigible romantic who is so lost that no living human can possibly match the surge in the heart. So, the surge in the heart is left to be alone. That way, at least it is complete.
When you direct that romance towards a living person, the direction of the surge is seized by the limit of the recipient. But the surge in the heart is the size of a tsunami, and most people are not even Shiva enough to handle a river, let alone a tsunami. The choice, is to tame the tsunami and to find something like fulfilment, or to let the tsunami be and to attempt self annihilation.
So far, the self annihilation part hasn't worked out. But the tsunami remains. It cannot a river be.
