I think the commenters thus far have been a little off, and I think this song is more straightforward than you're making it out to be - it's less about the girl per se and more about Joey's process of grief.
"Yesterday's moving" aka distancing himself from the situation ("It's easier to locate a better nest / Tell them you never lived in such a mess"), "Today is denial" aka denying his previous feelings or that he's jealous of the new love interest ("Can't expect the creep to stay long / But he's not the one who pissed her off") then "Tomorrow is heartbreak" aka acceptance, where the song gets a little more vindictive as he's crushed by the situation ("Emily you'll always be alone"). After acceptance, he wishes it never happened at all ("Sorry I bit that hook").
Side note: who is Emily? Is Emily "E" from "E Dagger"? She's also referenced in Name Dropping off of Hoss ("Emily had sex with Joey").
