The speaker in "The Raven" loves a woman named Lenore. That's part of the nice balance of this poem. At times it's almost campy and over-the-top, with all the elaborate rhyming and fancy vocabulary. At its heart though, the poem is about a man who only wants one thing in the world: to be back with the woman he loves. Sadly, that's the one thing he absolutely can't have. This is a pretty depressing look at love; and, while Poe never even uses the word directly, love still pervades this poem.
In this poem, the speaker talks about his lost love, but he is really consumed by his own sadness and his strange psychological obsession. The idea of love is buried under his self-involvement.
