A good book that might help is "Getting Back Together," It's all about separation and easing back into... well... getting back together. I really like this book because it helped me realize how healing and healthy separation can be. I do think it's important to wait until he's ready. If not you risk another future separation and you start yo-yoing (I've been there and done that!!! And would prefer never to do that again!!!).
Anyhow, good luck to you. I think staying apart, but staying friends and perhaps dating can sometimes be a really healthy way to build back up.
There is no arriving, ever. It is all a continual becoming.
