Well look at positive side too. No kids involved, so you'll get s clean break. You found out who she really was relatively early on in your marriage, think if she did this stuff behind your back and you found out 10-15 years later.

It's not going to be easy, it's not going to be sunshine and rainbows, but you gotta believe you're better off. And you will be.

I think splitting the cost 50/50 is more than fair. If she resists and gets pissed then guess what, too bad. In the end it'll cost you $1000-1500 to get rid of her forever, pretty cheap :p

You'll be fine. Just concentrate on making money, and making yourself better. You want to be desirable, and the best person you can be. Ultimate revenge is 5 years from now when you're well off and happy with someone else, and she's still slumming around being the party girl and has no future, you can say "yeah I'm def better off"

Living well is the best revenge
