Consensus is NOT to give your spouse DR or let them know about this web site.
You have given your spouse the book. That is OK. Right now with an A going on, he is most likely not receptive to doing anything that works on fixing the M.
If you can, get it back from him. It is better if he does not have YOUR PLAYBOOK. Go get it. After you get it, if he ever asks about it, which I doubt, say "I decided I wanted to read it again." You can offer another R book like "5 love languages"
If you can't find it, ask for it back. Example: "I would like to re-read some parts of it".
