Montana,
Hi. Welcome/sorry.
First the only "companion' book would be DivorceBusting. I've never read it, but I've read on these boards that DB is several years older than DR and that DR is far better.
That being said, DO NOT give DR to your spouse, or let them see it or even know about it.
1) Why give one's strategy away, give yourself away?
2)Your spouse will see your changes as phony and formulaic,

I may not have much time today as my family has our Thanksgiving Day today. But others will be by. In the meantime, Post info.
Are you H or W? How old, How long together, how long married, children?, etc. Who what where when why, details and timeline of exactly what's been going on.
Read "Quotes Found on Divorce Busting (II)" at the top of The Newcomers Forum.

With fruit, with weeds even; but gather them
In the one garden you may call your own."
