I've always thought that in this poem the poet wanted us to see him as pathetic and arrogant. Like the friend who's telling you about his woeful tale of love lost in spite of all he did for her, when you find yourself having to nod in sympathy whilst all the time knowing full well that he brought his misfortune on himself. Kavanagh is standing outside himself here and observing his own romantic ineptitude (he laments it in the poem too when he says he loved too much). He does what many a spurned lover does when he insults her right at the end of the poem (and augmenting himself at the same time!) I'm sure he wants us to see that as diminishing him. I think some of Tom's rhyming scheme is stretching things a bit. Danger/walked? Street/we? (coincidence, surely!) Wooed/should? I can't make those two rhyme! Me/hurriedLY? Hmm. I think Kavanagh just rhymed where it happened to fit but just didn't bother to hunt for alternatives where it didn't, and I think the poem's all the better for that bit of freedom.
