Let sleeping dogs lie as the old saying goes here, dear. You made a mistake, @AngelAngel, why go barking up the wrong tree by Beating yourself up over your Error of your sway way.
If you don't plan on Cheating again, and I am trusting you won't, for you are guilty as sin in your own mind, then Forget it right now, pucker up, save your relationship and with saving the Day... Paint the town red and have a blast.
Even eventually if you would spill the beans, it will definitely cause a big problem and you may not Only lose Her, but the Beautiful memory of a dance and a chance for romance that only comes Once in a lifetime...
Go, my friend and sin no more.
Good luck. xx

You cheated. That terrible. But mistakes happen. that doesn't make you a horrible person per se. I mean, you obviously recognize you're wronged her... you need to come clean with her before you ruin her prom. There's no winning here. You fucked up. you know that. You need to do the most decent thing you can do right now and just be straight with her. If she dumps your cheating ass, at least her prom won't be one big lie. And it'll just go to show that even if you pull a totally dick move sometimes, you do have good in you.
Tell her. It's the right thing to do. And hope she gives you the second chance you likely don't even deserve. That's all the advice I can give you
