Beautiful poem. the sadness of the obvious longing is superseded by the irony of certainty. Self love precedes loving others, they say (lack of it may preclude loving others). This speaker thinks highly enough of herself/himself as to promise bliss in her/his company. That's promising.
An ocean of feelings need not drawn their travelers. It can and should allow them to shorten distances and get away from sadness and closer to happiness.
