There's a thing with women that they DO remember everything. Once you're married, everything pre-marriage doesn't seem to hold weight(at least with my wife) but everything AFTER the "I do's" are fair game.
Gentlemen, SP1 is right... Women are fickle. It's best to learn it, love it, and live with it.
If you're only the bad guy for a day, consider yourself lucky. There are some that have it worse than you.
