OF, I don't know if I can add much to what has already been said but what if you just invited her out to lunch? Take her to a nice restaurant, talk about random fun stuff, ask her if she's happy and say you're glad to hear it etc. Then tell her divorce is not something you want but you have to do this for her. Tell her about the finances in a nice way. Then tell her to give it a thought without the outside influence, tell her to think about how she felt about you in the beginning before she gives you the answer.
You don't have much to lose at this point, show her you're a nice caring person and leave the rest on her conscience. This is how my situation went and it worked for me. However, in my case I guess what also made my W reconsider us is the fact that she'd learnt her lesson the hard way already...
OF, either way I know you're not only strong but quite smart as well - you'll be just fine. Worse comes to worse money is money, it can be made again...surely it's not ideal but few things in life are.
All the best to you my friend.
