A couple of books that helped us were:
"The Dewey Color System for Relationships" by Dewey Sadka was probably the most helpful (and creepily accurate I might add....). This book helped bring to light some reason behind why we each think and act like we do.. Interesting
The other is "The Five Love Languages" by Gary Chapman. This book is written from a more spiritual standpoint, which was a little hard to get through, but the overall gist of the "languages" that he points out was helpful.
"Wovon man nicht sprechen, darüber muss man schweigen." -Ludwig Wittgenstein
Me- Linkin Park- the husband. I am the youngest, fast paced and admittedly full of issues.
Nina Simone- our wife- slow, gritty, and sexy like a smoky piano bar and a glass of brandy.
Led Zepplin- our wife - a rocker little tomboy that loves with everything. All she's got or nothing at all.
