Why is "The Love Song of J. Alfred Prufrock" a love song?

In a typical love song,
the singer might tell their loved one just how much they care, that they cannot live without the
other person, or that their life will not be complete without that other person's love in
return. However, Prufrock's love song does not feel particularly love-songlike at all. He never
says how much he loves this woman with whom he attends the party and never states that he cannot
live without her. Instead, he considers asking her an "overwhelming question" --
possibly if she loves him too, or even if she will agree to marry him -- but he never actually
asks it because he is too afraid of potential rejection. The typical singer of a love song makes
themselves vulnerable as they confess their feelings, but Prufrock simply cannot bring himself
to do the same. Therefore, the title of the poem is ironic: he does not have the courage to sing
a real love song, and this is the best he can muster.
