Wow!!! good for you! One thing I really like about the book is how is depicts separation as a healthy thing. My husband has a history of needing to "get away" from the marriage. This used to really upset me and I'd try to pull him back in quickly. This book gave me a whole new appreciation for separation. Also, how common it is! That was an eyeopener for me too. Sometimes you think you're the only one going through all this stuff.
One more thing, you may be far along, but what about your wife?
I think there's a lot of wisdom in taking time, and going slow and steady with reconciliation. Like taking the time to build it strong and secure.
There is no arriving, ever. It is all a continual becoming.
