Absolutely. It explores the 'imprint' we received while growing up in our own families and how we carry that with us into all our future relationships. It not only applies to current relationships, but will give you insight to how your parents raised you, and also how you can avoid some of the pitfalls as you 'imprint' your own children as they grow. It can be extended so much further than just within marriage. You have not doubt heard of the 'Love languages', well these authors promote the 'Love styles'.
I think the authors chose a target area of marriage for the focus of the book, maybe they thought "How We Love" by itself might be a bit too ambiguous.
Enter the book title dot com and you can get an idea of their ministry.
