Okay, my theory doesn't complete fit just right, it's not one of Cinderella's glass slippers (pun intended), but here it is:
I get the feeling that in this song the guy (Brian Fallon or just a fictional person) starts out thinking that he's the girl's main guy and she's cheating on him with someone else ("I guess you need a little sugar 'cause you always wander around," "Only I know, I know you get lonely") and then he realizes that HE is the other guy ("I saw you walking with him, down the steps that I walked you in. I got hurried by midnight, with slippers of glass and perfect fits") because she's in a hurry to get back home before her husband or boyfriend does so he won't find out about her affair, and to me the chorus is the guy who was the other man in the relationship is telling her not to ask him for any more dates because he knows what's going on.
