Absent from thee is a satirical approach to the traditional love poetry, which gently mocks and makes light of the genre.  The speaker ruminates on his serial unfaithfulness, all the while admitting that while he does love his partner, he also has desires he cannot ignore.  Beneath the humorous tone, there is a sense of struggle; the speaker is potentially unhappy with some of his life choices, how he frequently indulges with ‘unblest’ hearts and only finds true peace and contentment with his real love.
