The above are all good recommendations.
A book that I just read (I am also engaged) that I think will help alot in the emotional aspect of marriage, is the “Five Love Languages.”
It speaks of how people show love and feel loved in certain ways. Therefore, if your spouse feels loved in one way, but you show love in another way, the spouse may not have their emotional love needs fulfilled. This book will help know your own love language and your spouses love language so as to fill each other’s emotional needs.
For instance, my fiance’s primary love language is physical affection. My primary love language is quality time. For awhile I was not meeting her needs (I do not come from a touchy-feely, hugging family, my fiance does) and it put a strain in our relationship. She could not put a finger on it, but once she read the book, she told me to read it. I have since been working on ways to fill her love tank and our relationship is soaring.
Our goal is to work on all five love languages so that we can fill each other’s emotional needs abundantly, and also be prepared for the differing love needs of our children.
Anyways, I highly recommend it. The author is a christian (it is quite clear in his writing), although I do not know if he is Catholic or not.
God Bless.
