I found that book very helpful, na. I've been trying to heal the hurt I caused my H by rejecting him sexually for months, since the ILYBINILWY last fall. There was a period during which I knew he was considering leaving but he hadn't actually said that he was going to do it yet, and during that time we continued to have sex. I got the 'don't want to lead you on speech' to which I responded by saying that I felt very badly about the way I had been in the past and that I wanted to offer him 'free access' for myself, to help with the regret I was feeling.
We have continued to have sex even after he rented an apartment (to which he never did move) and reading books like the SSM and For Women Only (Shaunti Feldhahn) have helped me find other ways to shift my attitude and SHOW my H that this part of our M has changed and will not go back to the bad old days. He has often said that he will read a book, only to either not altogether or start it and never finish it - it's not really a way he gets information, although he reads tons of fiction - and so in my house, I do the reading and either discuss a very compact version of it with him. (I can occasionally slip in a small R talk if I disguise it as "here's another things I've realized/noticed". This often includes an apology, as I sincerely feel terrible and wish I had some 'do overs'.)
That's a lot of blathering to say that even if he doesn't read it, you can still find a way to use the information to make your R better.
