The SYMBIS book has been great for my boyfriend and I! Purchasing the workbooks to go along with the book really makes you take an active role and apply what you're reading. I'd definitely recommend it!
I highly recommend this workbook and the matching one for men. There is also a hardback book and video on the same topic by the same authors: Drs. Les and Leslie Parrott. I have had great feed back when I teach it as a pre-marriage class. The workbooks are a suppliment to the video but can be used by individuals to kickstart conversations on subjects that NEED to be discussed before marriage. Great Program.
