That a wife could give to a husband to help him understand what her needs are, what book would that be?
I agree.I think it won't be a good idea for you to just give him a book like that even if you find it. He will feel offended and he won't read it.
After 22 years of marriage and facing an empty nest my wife asked me to read 2 books, "Its (Mostly) His Fault" by Robert Alter, and John Gray's "Mars and Venus in the Bedroom".
I would recommend two books by two different authors, but the two books complement each other. Read both. The second book (love languages) isn't that long and the first book is very straightforward.
Has your husband asked for your help?
For the record I am getting ALL my needs met now and my husband didn't read not one book. All change starts with YOU not your spouse.
So many to choose from.... the specific issue can change the book recommendation...
