There is a very helpful book that deals with issues like the above stated. It is called, "Preparing to Be His HelpMeet" by Debi Pearl. I believe this book would be incredibly useful for her! I have read it, and have learned wisdom. In one chapter she speaks about 3 different types of men: Kingly, Visionary, and Steady. My dad says, it is scary how accurate she is! This might be helpful for the young lady, to understand better her fiance.
I love how from the very first chapter, she emphasizes prayer, and then later on how we can always ask God for wisdom, and will receive it!
