Oh no, try not to worry too much. Just have a blast with your friends. That's the best revenge is when someone you loved sees you having a great time without them. (I'm so mean!) Sending good "$$$ and no seeing the ex" vibes your way.
hmmmm....hey, at least you know you''ll look hot in your vegas clothes! hehe. VEGAS is so huge, hopefully you wont run into him. have fuuuuuuuun. remember: what happens in vegas stays in vegas!
this really sucks. That's the thought that came to mind. Have fun in Vegas & don't worry about him - I'm so jealous - you are going to have such a good time!

You know what? This is just more incentive for you to have a kickass time in Vegas. If, by some rare chance he does run into you, you'll be having so much fun and looking so freakin' hot, he won't know what hit him. And he will just bounce right off you.
And you probably won't run into him. There are too many people in Vegas for that to happen. It's possible of course, but I doubt it's likely.
Have fun and be as wild and crazy as you can be!!!
