So here's a dillemma I could use some advice on:

Blacked out partying last weekend and hooked up with an ugly chick.. ok, shit happens..

I'm into the whole honesty thing, and I need to break it down to my girlfriend.. the question is how. I'm going to see her this weekend, which is her college graduation. I figured it would probably be pretty fucked up news to deliver when she is celebrating wasting the last 4 years of her life, so I'm going to wait until after that..

Now before you figure me for the complete asshole keep in mind that she isn't an angel either... she has (almost) cheated on me once before.. she called me up drunk one night telling me how she almost went home with another couple, and how they were pretty close to fucking at whatever club she was at...

Any ideas?
