I already love her for making him squirm. Whenever she's in town, he sleeps with one eye open and ready to run with his tail between his legs.
Did you want to hammer out any details surrounding their days of courtship? I'm game to say they both knew it was a fleeting thing, he just so happened to cut and run first and that's always stinging to one's pride, or he could've made a lot of promises that he never intended to keep. Most likely in the form of a song he claimed to have written just for her (spoiler: he only swapped out the names).
