I would second the recommendation to set the custodial and financial arrangements in place right away. It was the best thing that I did. At the beginning, I think the WAS/WS is often eager to move on and easier to make arrangements with. You shouldn't hesitate to get it out of the way. I know it's a bitter pill to swallow, but once that's settled you can focus on rebuilding your life. And getting the custodial and financial arrangements settled doesn't necessarily speed the divorce process along. I'd also go one step further than putting things in writing. You should be able to finalize those matters with the court while the waiting period (if your area has one) ticks down to zero. Then, you're done with the hard part of the court process and can focus on the emotional healing and recovery.
