What is the poem "Loving" about?

The opening reference to the “balloon of gauze” suggests
that lovers really create their own separate world even though it may be visible and
perceptible only to their eyes. Because gauze is also the stuff of bandages, could the
poet be suggesting that love might also be an illness, a wound? One might remember that
Eros, or Cupid, is usually pictured with a bow and arrow, which he uses to wound people
who then fall in love as a result. The references to veins and blood make the point that
love is internalized and also deeply physical. Line 15, “We are in here together,” gets
this idea across well.  The concluding reference to the “balloon” growing “up around us
again” suggests that the speaker is referring to the fleeting nature of the intense
experience with love. The lovers may be “torn into two people” (line 22), but their
experience of love will grow up again, and though invisible, it is also binding—a true
transformation of the persons in love.
