Love, Though for This You Riddle Me With Darts

Millay's poem is a tongue in cheek demonstration of the principle of revealed preference: What individuals want is demonstrated by what they do. She insults the god of love in terms designed to imply that she does not want what he is handing out ("Who still am free, unto no querulous care/A fool").

The predictable result of insulting the god of love is that he will shoot her. Being shot by him means falling in love. So the fact that she insults him implies that she wants to be in love‚Äďas she concedes in the final couplet.
