"Men are from Mars, Women are from Venus", you can suggest she search it in the Watchtower Library to see if it is mentioned there (which it is, in a positive way. The article that mentions it actually uses the information in the book as the basis for the article).
Good idea Pirata, it would be an opening of the door to bring in information not written by a writing committee ruled by the GB.
I have skimmed through much of the book and read chapter 11 as suggested by jgnat in an earlier post and I really do not understand why the study conductor would suggest this book for a study to read with an 'unbelieving' husband. I had spoken with the study conductor's husband in the past (who is an elder) and I know they both realize I know a lot more about the JWs history and doctrine than they feel comfortable with.
It appears that the present 'study' is a read of the family happiness book, they are on chapter 2 where it starts to discuss agape love.
