Divorce after Twenty years together Community Group
I want to start something for those of us that were married for a long long time. I think that we face a little different issues than those who were dating for a few years or even married for shorter period of time. Being married for so long we have older children some have grandkids dealing with teenagers and their reaction to the divorice empty nesters dating after 40...

Filing for divorce doesn't necessarily mean you are going to litigation -- but it DOES put some teeth into it.
One of the earlier responses here mentioned hiring a forensic accountant. That can be exhorbitantly expensive and I seriously doubt that it's necessary in your case. Usually an accurate "paper trail" can be tracked through income tax returns and bank statements. But again, unless you have actually filed for divorce, you probably won't get anything more than he has offered so far.
IMO whether the divorce is fault or no-fault, the best way to manage divorce is to EMPOWER YOURSELF! Knowledge is power! There is so much good information available through the internet AND at your local courthouse there is no excuse for feeling as if you have no control over the situation.
At the end of the 18 Months of Hell it took for my divorce to be final, my attorney gave me a hand-lettered honorary law degree. She said, "You did all the hard work; all I did was push the papers around." I was quite amused because while I had worked in a law office for a year DECADES earlier, all we did was real estate law. But it was my natural curiosity and my drive to be my own best advocate that had me digging -- through old financial reports, case law, and even doing some of my own private investigating. In the end, I got everything I had asked for from the get-go. It was the most difficult task I had ever taken on, but I was dead serious NOT to let that stupid, selfish man ruin the rest of my life!
It's not easy, believe me -- I dealt with a stubborn hard-head for 9 long months before I ever filed for divorce. But by that time, I had had enough of his crap to last me a lifetime. That's when I (to quote Hurtinandhealin) "took the leash off my attorney" and things went from zero to 60 in very short order.
In any event, Goldengirl, good luck with the mediation -- but do NOT under any circumstances -- allow that temporary hearing on the 16th to be cancelled because even IF you are able to strike a deal in mediation, the document still has to be fully executed and approved by the court before it's "written in stone." A lot can happen between now and then....
Although it's a tad premature, Im beginning to see a light at the end of this horrible tunnel I've been in for the past year. If we can agree tomorrow, we will basically be done, as long as everything's in writing and signed off on.
