re: How do people cope with separation or divorce?

Go to therapy. It helps. Even better, reconnect with friends. You're going to need that support network.

Second, get back into shape. Marriage has a tendency to have you rest on your laurels. Wear better clothes too.

Third, this is now a business transaction. Treat it as such. Don't take it personal if she gets out of line, handle everything through your attorney. If you have kids, do your best not to ever bad mouth their mother.

Good luck and God speed. It gets better.
