jesus, did really make out with her?

holy crap, I know I got bombed at the "holiday" party at work (sure about this part) and I think made out with a chick (90% sure about this part).

Every other year I would break my arm patting myself on the back, but this year I moved in with my girlfriend. Anybody know how to deal with this? Both the girlfriend and the girl at work? I aint breaking it off with my girlfriend, I just got boozed up and did what was natural.
