Okay, I'm stepping in late, but I have to give you my comments because I consider myself to be a male's advocate. It's a necessary role to play because women have lost all sense of decency and responsibility in this country.

I know this hurts/fuckings sucks, but consider yourself lucky. You found out the truth about women. No, not all women are like this - but MANY are. You now have the upper hand. Use that to your advantage.

First thing first, get your head on straight as much as you can - find your own emotional stability right now. Do not go into anything with an emotional state - women are masters at emotional manipulation - if you show weakness here, you are fucked. If you tell her what you did, you are also fucked. The typical woman will take what you did and use it against you. The blame for everything she can think of will be placed at your feet, she will not take responsibility for anything (in fact, she'll twist the whole conversation so that it's not even about her misdeeds, it's what YOU did wrong as a man) and after this conversation of insanity, she will feel like she is justified and guiltless. And you will think afterwards 'wait, what the hell happened, she IS THE CHEATER."

To echo my man's thoughts here:
