I have a live version of this song and John Mayer explains what it is about. He says that is having the right time to end the relationship but something comes up. Like he said "Well, I told her I would go to the Peter's wedding and I can't break that." Hence, all the holidays are the reason why they stay together (Nobody wants to be alone at x-mas time), but after St. Pat's there is no reason. I don't know if that helps but thats how he explains it.
